Cracking CS50P: Thinking Through "Making Faces"

Dilesh Zingare — Sat, 19 Sep 2026 04:11:32 +0000

Welcome back to my new series of "Cracking CS50P: A DevAdvocate's Python Guide", today we are going to dive into how I tackled the third problem in Problem Set 0: "Making Faces" (faces.py).

If you didn't read the previous article I mean Playback Speed or playback.py then trust me you are missing the important detail in the python language. And as you know I am here to guide you in how to solve the problems I am not telling the exact answers to any problem set because you have to learn it by yourself.

**_

Recap of 2nd Article playback.py........

_**In the previous article we saw how to replace any "str" to something we want it to replace in to. But only if it's a string not a number or a float or etc., Note this one out this is a thing anyone could forget about OK.....
This article is also the same as the previous one but this time we have to replace the more than one str into something so it's going to be intresting so hang on tight.
Let me tell you a secret, As the first and the second mistake I misunderstood this one too and print out the exact statement like given in the example section. (e.g."Hello 🙂") It is so funny I couldn't resist after realizing that and I begin to laugh.....

_**Let's start 3rd Article faces.py........

**_
In this part we are going to see that how to instruct the system to replace more than one string to something else. Let's get started, In previous part we use .replace( ) syntax in this part we can use this syntax and other syntax too. So, for this we can use "n" number of .replace( ) syntax for "n" number of replacements like [.replace("/", "?").replace("_", "=")] in this case we are replacing( / to ? and _ to = ) and also we can use a variable to assign the values of replacements and use

for target, emoji in replacements.items():
user_text = user_text.replace(target, emoji)

from this we can use only one function and still get the value as the previous syntax.
So, I guess that's it for today if any has any doubt feel free to ask in the comment and if not then you can see the YouTube lecture video on my channel. See you all in the next article of CS50 intro to Python.

Slowing Things Down: What CS50P’s "Playback Speed" Teaches Us About Clear Tech Communication

Dilesh Zingare — Sat, 19 Sep 2026 04:08:45 +0000

Welcome back to my new series of "Cracking CS50P: A DevAdvocate's Python Guide", today we are going to dive into how I tackled the second problem in Problem Set 0: "Playback Speed" (playback.py).

If you haven't read the 1st article in this series then, My Bro you are missing the important detail because it's the first article in this series so trust me you don't want to miss it.

**_

Recap of 1st Article indoor.py.........

_**In the 1st article we saw how to convert any alphabet case to Upper Case, Lower Case and Title Form and how to remove the any whitespace from the users input.

.lower(): This converts all uppercase alphabets into lowercase.

.strip(): As a bonus tip, you can chain this method to remove any accidental leading or trailing whitespace from the user's input.

.upper(): This converts all lowercase alphabets into uppercase.

.title(): This capitalizes the first letter of every word. (e.g., "this is cs50" becomes "This Is Cs50").

Let me tell you a secret, As the first mistake I misunderstood this one too and print out the exact statement like This...is...CS50. and This...is...our...week...on...functions. this is so embarrassing I could......
**_

Let's Start 2nd Article playback.py..........
_**
In this part we will see that how to slow down in text. So, for slowing down in the pace of text we use .replace() syntax. What's it does nothing much it only do as replace something into the instructed one. So, in this problem we have to replace the space character " " in the sentence into triple dots "...". Why only this? Because it's instructed in the instruction section of the problem set 0.

If you want to check how it's exactly done then watch in my YouTube Channel.
If you have any doubts about this article feel free to drop a comment and I have uploaded the YouTube lecture video so watch it. See you in the next article.

Beyond the Syntax: What CS50P’s "Indoor Voice" Teaches Us About Developer Empath

Dilesh Zingare — Sat, 19 Sep 2026 04:06:14 +0000

Hello once again, it's been a long time since I have written an article because I was busy in finding something that will help me to pursue my goal to become a Developer Advocate. And guess what I found one course that is totally awesome. It's called the Harvard CS50 course, There are more than one course playlist like CS50 Python, CS50 R, CS50 Business, CS50x, CS50 Web, CS50 2D, CS50 AI, CS50 Cybersecurity, CS50 for Lawyers, CS50 Scratch, CS50 SQL. You can find them on their official website.

Today, we are going to dive into how I tackled the very first problem in Problem Set 0: "Indoor Voice" (indoor.py).

**_

Let's get started......

_**So moving on to our today's main goal to How I complete the 1st problem in the problem set 0. If you are a python guy or girl trust me it's pretty easy to solve this type of problems instantly but if you are not so don't get so worked up because that's why you are here. As long as I am here so don't fear. Let me tell you a secret 🤫, I was under the wrong impression that it's a child's play to solve this problem but I was so naive that I underestimated that problem and as the demo says I printed out the exact sentences that they told me to do but that's wasn't the real problem and I actually write that and submitted and after some time I realised that I have done a mistake very terrible that anyone could read and laugh at me as I write that code. So, this article is for you all to saving you from that same mistake that I have done in my past.

So, In the instructions there was written that everything you written in the input function in the lower or upper cases no matter what you type in that has to be printed out in the lower case, Numbers don't have case so, .lower() safely ignores them. But I didn't read all of the instructions and I fail. Then we can correct that mistake from the syntax called .lower() it's only work is to convert all the upper cases Alphabets into lower cases. And if you want you can also use a syntax called .strip() it's work is to remove any whitespaces in the input function.

.lower(): This converts all uppercase alphabets into lowercase.

.strip(): As a bonus tip, you can chain this method to remove any accidental leading or trailing whitespace from the user's input.

.upper(): This converts all lowercase alphabets into uppercase.

.title(): This capitalizes the first letter of every word. (e.g., "this is cs50" becomes "This Is Cs50").

And that's it. Our today's article is over I will see you in the next article soon. So, Good Day till then.......

If you have any doubts feel free to drop a comment in the comment box below. And i have also uploaded the lecture video of 20 min on my YouTube channel for you so be my guest to open and watch that too.

And here's my GitHub URL for an example of how to write that. [https://github.com/dilesh596\]

How I Built a Visual Python Calculator in the Terminal

Dilesh Zingare — Sat, 19 Sep 2026 04:01:05 +0000

Hello and Welcome to my new article about Calculator made with a Python script it is a simple calculator for now but we will be advancing it further more. So, Hang on..... I am Dilesh Zingare and this is my new article about How to make a calculator from python.

**_

Let's Get Started.......

_**First of all you will have to visualize How will your calculator works and How will you write a script of it. These are two main goals that you have clear before writing the code it is essential to be clear toward your idea.

For better idea here's my raw code URL from github :- [https://github.com/dilesh596/ascii-cli-calculator] Now you can see how the simple calculator looks like now you can visualize it too, right. The only thing you will have to do is coding and it is so fun, isn't it......

After you visualize how your calculator works it's time for coding. Let's get to it..... First of all you will have to ask the user to enter the first number of the calculation and then the operation symbol and then at last the last number although It is a simple calculator it can only do one operation at a time. We will improve it eventually don't mind the present form see the big picture, Ok..... We have to use if, elif and else operations to differentiate between the operations such as Addition, Subtraction, Multiplication, Division, etc.,

I Built a Restaurant Website Using Only HTML – My First Frontend Project Series. Part-4

Dilesh Zingare — Sat, 19 Sep 2026 03:54:43 +0000

Hello and welcome back to my 4th part of My First Frontend Project Series. I am Dilesh Zingare and, If you didn't see previous 3 articles then you are missing something important. I have uploaded lectures videos of each and every article I uploaded so don't worry about anything.

**_

Quick Recap of 3rd Part......

_**
In previous part we have learned about CSS Style Tag. We saw that what are the Selectors, Properties and Values of Style Tag. In this Article we will see that, How Buttons works and How to apply them in our HTML file. Except that is the part of CSS too......

_**

Let's Start 4th Part.....

**_
Button is an HTML tag and we use it to create the clickable button in Body of HTML file. For that we have to use button tag and you know how to apply any type of tag to an HTML file, Right. In the button tag you will have to write a type of Properties and it's value to properly command the computer. Like (button type= button) here is the link from you can watch how to apply the button tag.
[https://github.com/dilesh596/The-Bite-of-Soul/blob/main/Website.html]

Don't forget that we can only use <> this parentheses in HTML.

From CSS Style tag you can design the button as you like.....

That's it for today and I think this was the last article of this series. Don't forget to apply this on your website. And after you have made the real life project make sure to comment me link of it. Good bye till next article...

I Built a Restaurant Website Using Only HTML – My First Frontend Project Series. Part-3

Dilesh Zingare — Sat, 19 Sep 2026 03:50:29 +0000

Hello and welcome to my 3rd part of My First Frontend Project Series. I am Dilesh Zingare and, If you didn't see previous 2 articles then you are missing something important. I have uploaded lectures videos of every article I uploaded so don't worry about anything.

_**

Quick Recap of 2nd part....

**_
In previous part we have learned about how heading tags and divider tag works. What are the attributes of div tag and what can be the values of each attributes..... And I said I will be teaching style tag later on! So this will be the part where we learn about CSS and style.

_**Let's Start 3rd Part.

**_
CSS stands for Cascading Style sheet and like name said it is use for styling the page (output). We can style it like crazy like this..........

And this is only a beginning, we can do much more fun staff from CSS, which you didn't even thought about. So, let's get started.....

If you want you can use style tag in HTML file or you can create a new CSS file differently, but it have to has in the same folder as your HTML file. If you create a different folder for CSS file then you have to work more to provide the path of that folder to your HTML file folder :-
[https://github.com/dilesh596/The-Bite-of-Soul text ]: you can use this link as a reference for style tag. I didn't create a different file for CSS because I think creating a different file for only style tag is drag instead I add Style tag in HTML file it is much easer, That I think at least.

For adding Style tag to a specific area we have to create a selector which will apply things to that specific area which you created. Selectors can be anything such as a, b, c, d,......, z or body, header, footer, etc. Then after you created the selector then add space and add curly brackets { } then add styling attributes like color, background-color, background-image, text-align, padding, text-decoration, text-position, font-family, etc.

Remember that I write color not colour and I didn't add space for adding words like text align I write as text-align.

About values of attributes.
background-color: or color: black or white or pink or brown etc.... text-align: or text-position: left or right or center text-decoration: none or underline or overline or dashed etc...... font-family: arial etc..... background-image: url('data:image/jpeg.................') it will look like this, You have to paste online URL of image from Google the structure till URL('......') will be same as here the url can be vary. But data:image/jpeg will be same for every url.

Example:
header { background-image: url('data:image/jpeg;example.com'); background-position: center; color: whitesmoke; padding: 100px 30px; text-align: center; background-color: black; text-decoration: none; font-family: Arial, sans-serif; }

So, That's it for today, See you at the next article. Don't forget to make use of what you leaned about in all the articles. Good bye till then. If you have any kind of doubt just ask me in the comment section don't hesitate.

I Built a Restaurant Website Using Only HTML – My First Frontend Project Series. Part-2

Dilesh Zingare — Sat, 19 Sep 2026 03:43:39 +0000

Hello and welcome to my 2nd part of My First Frontend Project Series. I am Dilesh Zingare and, If you didn't read the 1st part of the series believe me you have to read that you are missing something important. I have uploaded Video Lectures of every article I uploaded so don't worry about anything.

Quick Recap of 1st part.

In previous part, we learned about fundamental structure of HTML and how to link two HTML files together by anchor tag. And after that I provided you the link of my entire project on github.

Let's Start 2nd part.

In this part we will see how to build a webpage from scratch. If I be honest with you I don't know if this webpage will complete in this part, What ever We will see later on. Now let's get started:

First of all I will provide you the image of the webpage I have build and then we will see my raw code after that we will continue with how to build it from scratch.

This is how it will look after you build the code. And these buttons are clickable hmm. Don't misunderstand them as only mere text.

This is the raw code.
And here's my github URL for the raw code.
[https://github.com/dilesh596/The-Bite-of-Soul/blob/main/Website.htmltext]

Don't slack off ! You have to read all the code carefully and ask any doubts you have in your mind in comment section.

Explanation.
You know the fundamental structure of HTML right. Now we will start from basics of how to build it. And we will cover style tag later on! Because it is CSS part.

In case you are wondering lang means Language and en stands for English. And meta charset is for informing that how to translate the binary data (zeros and ones) into human-readable text and symbols in the output of our code. h1,h2,......,h6 are heading tags which are used to give headlines to our text like big and small. Remember that h1 is the biggest tag there known and h6 is the smallest tag there known. And div stands for divider it's mean just like it sounds. It divides as a section at the page and class is an attribute of div tag, Attribute of div can be class, id, style, etc.

So, that's it for today see you in the next article. Good bye till then and don't forget to make use of what we learned today. I will soon upload the lecture videos so hang in there for now.

I Built a Restaurant Website Using Only HTML – My First Frontend Project Series. Part-1

Dilesh Zingare — Sat, 19 Sep 2026 03:35:56 +0000

Hello and welcome to my new Article. This article is too big to fit only on the one page it could be 50,000 to 90,000 letters long or may be worst that that so, I was thinking what should I do in case it is too big. If anyone want to read it they will be scared to the death after seeing the size of it so instead I break article in the several parts so anyone can read it in parts. Let's get started.

HTML stands for HyperText Markup Language.

CSS stands for Cascading Style Sheets..

In case you are wondering it is fully beginner level project using only HTML and CSS languages. And remember that I am here to teach you all from scratch after all the articles, I have uploaded the lecture videos for each article teach you where to start and how to start. You can count on me.

Today was only the introduction and main event will starts from next article of this series and believe me you don't want to miss it.

I am guessing that you already know the basic structure of HTML in case of you don't know I mentioned it below. Don't forget to take a look at it.

For now I will show you how to link other HTML files together.....

We use anchor tag ...... to link two files together and have to add href for linking it and have to add class= "button-link" it's work as clickable link. And like that you can link two files together pretty simple right.

Here's the original code I used for link files in my project..........

[https://github.com/dilesh596/The-Bite-of-Soul/blob/main/link.html] : This is the raw code which i wrote. So that's my github.com link. If you are curious you can look at my projects.

Quick Code Breakdown for Beginners:

<!DOCTYPE html>: Tells the web browser that this is a modern HTML5 document.

: The main container that wraps all the code on your page.

: Stores background information, like your page title and your CSS design styles.

: Contains everything visible on the screen, like your headings, text, images, and buttons.

<!DOCTYPE html>

<html>

<head>

<title>............</title>

</head>

<body>...........</body>

</html>

This is the structure of HTML code.

Ok then see you in the next article. Good bye till then.

The "DevRel Journey" Angle

Dilesh Zingare — Sat, 19 Sep 2026 03:24:42 +0000

Hello guy's I am Dilesh Zingare. And this is my first python code and also the first article ever written by me. So yeah I am excited and nervous to but as you know "Beyond fear lies victory." I just passed my 12th exam and I got really embarrassing percentage and as the meme said "Behind every I'm scared is I did it! So like that I am going to share my experience to all of my viewers and for reading this I want to personally Thank you all.

As title said I want to be a "Developer Advocate" and my journey starts from this article and code. I found about DEV Community from researching on platforms like Google and Insta (you know Instagram). So let's move on to the main event.

Now as per my project it's called as "Soul the Restro Waiter" and its amazing as you explore more and deeper. It can do a bunch of cool stuff like instant bill, serving order, serving menu, asking ad responding to different feedback and etc., As per now I am only recently begin to learn python I am not saying that I become a master or something like that It's just if I done anything wrong so you can correct me by using comments or etc techniques you know about.

So ok folks let's wipe the floor together. Here's my exact code from where I created that soul waiter.

So let's get started.

print("WELCOME to our restaurant! Please have a seat and ring the bell when you are ready to order.\n\n\n")

#After bell rings

print("Hello! I am soul, your waiter for today.")

print("May I ask for your name please?") name = input(" ").strip() print("Nice to meet you " + name + "! Here is our menu for today:")

menu = { "Garlic bread with herb butter": 20, "Bruschetta with tomato and basil": 21, "Caprese salad with mozzarella and balsamic glaze": 19.69, "Margherita pizza with fresh tomatoes and basil": 23, "Crispy calamari with lemon aioli": 22, "Stuffed mushrooms with cheese and herbs": 18.79, "Tiramisu with espresso-soaked ladyfingers and mascarpone cream": 20, "Panna cotta with mixed berry sauce": 19, "Cannoli with sweet ricotta filling and chocolate chips": 19.78, "Gelato with assorted flavour": 18.59, "Chocolate lava cake with vanilla ice cream": 21.99, "Espresso": 10, "Cappuccino": 12, "Latte": 13, "Americano": 11, "Mocha": 14, "Iced coffee": 15, }

print("MAIN DISHES:") print("""1. Garlic bread with herb butter 2. Bruschetta with tomato and basil 3. Caprese salad with mozzarella and balsamic glaze 4. Margherita pizza with fresh tomatoes and basil 5. Crispy calamari with lemon aioli 6. Stuffed mushrooms with cheese and herbs.""")

print("DESSERTS:") print("""1. Tiramisu with espresso-soaked ladyfingers and mascarpone cream 2. Panna cotta with mixed berry sauce 3. Cannoli with sweet ricotta filling and chocolate chips 4. Gelato with assorted flavour 5. Chocolate lava cake with vanilla ice cream.""")

print("FOR DRINKS:") print("""1. Espresso 2. Cappuccino 3. Latte 4. Americano 5. Mocha 6. Iced coffee.""")

def get_valid_order(prompt): while True: print(prompt) choice = input(" ").strip() if choice in menu: return choice print("Sorry, that item isn't available. Please enter the full name exactly as shown in the menu.")

def get_valid_quantity(prompt): while True: print(prompt) qty = input(" ").strip() if qty.isdigit() and int(qty) > 0: return int(qty) print("Please enter a valid positive number for quantity.")

order1 = get_valid_order("May I have your order please?") quantity1 = get_valid_quantity("What is the quantity of " + order1 + " you need?")

print("Anything else you want to order sir? If not, press Enter.") second_order = input(" ").strip() order2 = None quantity2 = 0

if second_order: if second_order in menu: order2 = second_order quantity2 = get_valid_quantity("What is the quantity of " + order2 + " you need?") else: print("Sorry, that second item isn't available. I will continue with your first order.")

print("Your order of " + order1 + " x" + str(quantity1) + (" and " + order2 + " x" + str(quantity2) if order2 else "") + " will arrive soon.")

total1 = menu[order1] * quantity1 total2 = menu[order2] * quantity2 if order2 else 0

print("Your total will be rs." + str(total1 + total2) + " only")

print("Please ring the bell if you need something. Have a nice meal.\n\n\n")

print("Please choose and write your feedback from options.")

print("#That was so bad #Bad #Good #That was so good")

feedback = input(" ")

fault = "That was so bad" or "Bad"

if feedback in fault: print("So sorry sir, can you please tell us what was wrong in our survice?") fault = input(" ") print("We will try to improve and make sure no one will ever suffer through that mistake again.") else: print("Thank you so much sir for feedback and for coming in today.")

print("Have a nice day.")

In case of you wondering I picked up the SOUL name from "Bleach" anime from soul reaper. I am one of the biggest fan of the anime industry. If you don't know about anime so you are missing a biggest flex in the world.

let's talk about work I built this code all by my self no help of AI or teacher OH! but i did watches the lectures and he was the hell of a teacher. But folks don't panic I am still here I will teach how to built code of any language from scratch don't worry. I will soon upload lecture videos of how I did built this waiter of ours from start and i will teach all for free.

And the fun part is that the videos length will never excided the 20 min time length no matter the the topic and i guaranteed you will never get bored and will have the fun with me. So that's it for today but don't forget to fix the bug from the code below.

Have fun. Bye.......

print("hello world!")

Goods = Water bottle, Bag pack, Tiffin box .

print(Goods)

Total_cost = 50 + 40+ 10

print("total_cost")

Why didn't it print total price it print total cost statement instated of value.

If you solve this bug comment below how many secs did you take.
