As a web developer fiddling around with JavaScript most of the time, I wanted to explore the territories of a different language and document the learning journey in the process. I decided to learn Python, one of the most loved and popular languages, something which had been in my wishlist for a while. It would be really nice I believe to explore the new possibilities that Python is so widely recognized for such as Data Science, Machine Learning etc.
I decided to split the learning roadmap in 4 weeks with each week dedicated to learning some specific areas of the language. As a developer, I know it is quite impossible to master a language in such a short span but a daily deliberate practice routine for the same duration is sufficient to start building interesting projects and build the foundations.
The Roadmap
Week 1 - Python fundamentals, basic syntax, setting up the developer environment, basic working principle, practice some basic coding and document the process.
Week 2 - Programming Paradigms → Object-Oriented and Functional Programming Patterns.
Week 3 - Python Decorators, Error Handling, Modules, Generators, Debugging.
Week 4 - File I/O, Regular Expressions, Testing, Scripting using Python.
Extras(Based on time availability): Data Scraping, Server Setup, Machine Learning Basics.
Documenting my daily progress would help me build a reference journal for future reference as well. I hope can act
as a helpful resource to anyone looking to learn the language as well 🙂
Day 1
I found this great video where the founder himself shares a brief story about the language.
Understanding about how Python works in simple words
Python is a high-level interpreted programming language.
What it means is that the python code needs to be translated (interpreted) by another software program which is called the interpreter that executes the code line by line and converts it into bytecode (very close to machine-readable code).
This bytecode is run by the Python virtual machine (gets installed when we install python) and then converted into machine-readable binary code which computers can process and perform the necessary action.
While installing Python, what we install is the python interpreter along with the virtual machine.
There are different variations of python interpreters:
- CPython - comes with the official installation and is written in C language
- Jython
- PyPy
- IronPython
Each of the implementations of their own features and trade-offs.
Versions
There are two major versions v2 and v3. In 2008, several major improvements were introduced in the language that introduced some breaking changes without considering backwards compatibility. The official docs now recommend using v3 and support for v2 would be ceased after 2020.
First beginner's program 😄
To keep things extremely simple at first, I wanted to play around with some basic hello world type code, to begin with.
I used the amazing online playground REPL to kickstart writing some python code and do a syntax comparison with JavaScript as well.
name = input('What is your name?') #promts user input in console and store in a variable
print('Welcome to the world of Python ' + name) # prints to console
comparing it with JavaScript
const name = prompt('What is your name?');
console.log('Welcome to the world of JavaScript ' + name);
Well, that's pretty much for Day-1! I know I have barely written any code. I just wanted to spend my first day in building the roadmap. Now that I have the language split into chunks, the goal would be to focus on the weekly goals and share daily progress about the same.
Have a great one!

This is cool. Am a beginner and i stated learning python for a month now and to be honest with everything else going through in my life it has been slow. Am happy i found this and it’s a good idea to have mile stones and it will be something am gonna implement in my journey too.
Good job
Thank you :)
Remember slow and steady wins the race :) Keep progressing at your own pace. The race is with our previous self. Getting a fraction better each day is more than enough :)
I stumbled on this by accident, and it caught my attention / interest because of the explanations being clear, concise and still covering most of the main underlying concepts.
This helps developing a better understanding (thereby making it much easier to remember) in a relatively short time.
I have worked on and off with Python and several of the libraries, decided to go through some comprehensive online courses to build a better foundation. This 19 step overview is now a key component in this as it helps putting the whole 'internal' narrative together very well.
Thanks for putting this one online
Thanks. Glad that you found it interesting :)
Hello, I am starting to work with Python, some code and small programs are already written, for sure this will help me to clarify some doubts, Thanks for the contribution, Happy Day
It's actually JavaScript (and not javascript) and CPython and PyPy and so on. Most of the links are broken, too. Please, could you have the content proof-read?
Hey, thanks for the observations! I appreciate that!
It was my first post in the series and out of the excitement of sharing with the community, I didn't quite proof-read it. I'll hopefully get better at that :)
I have updated the links and corrected the suggested names as well.
Thank you :)
Have a nice day,,,,
First of all "Thank you Sir", your doing such a great job, I love python coding, The way of your explanation is clear & awesome.
Thank you Sir
Glad that you liked it. Happy Coding 😊
I'm just guessing, but were you following the Andrei Neagoie's Python tutorial?
Yes. The roadmap is highly inspired by his lessons. I am a big fan :)
Thank you very much for sharing your experience with us, I hope you are doing great now with Python language
Good luck!
I am still exploring the language and yes I am enjoying it as Python has such a friendly syntax :)
I chose this style of language approach so as to have my progress documented for future reference and also share it with the awesome community. It has also helped me to restart blogging again :)
Me too I used JS before for web development projects, then I decided to move to Python language to explore the world of AI and Machine learning, I liked the comparison between JS and Python, and I think it is a good way to master Python as fast as possible.
Have a nice day
Best regards,
Great job in explaining the behind the scenes quite simply.
This looks great, I will be following this series.
