🌱 Hello DEV Community, 12th Grade Science Student Starting My Python Journey

Asara Khatun — Wed, 08 Jul 2026 03:56:38 +0000

Hi everyone, 👋 I am Asara, a 12th-grade science student from India with a huge passion for technology, Artificial Intelligence, and Data Science.
I have always been fascinated by how coding can be used to build scalable solutions for real-world problems. Recently, I took my first major step into the tech world by starting to learn Python. I have just successfully completed my first basics course—getting my hands dirty with variables, loops, and basic logic—and I am incredibly excited about the journey ahead 🐍💻
My ultimate goal is to strengthen my programming logic and start building practical, real-world projects that can make a positive impact on everyday life. While I am enjoying writing small scripts right now, I know that transitioning from simply understanding syntax to actually developing full-stack or AI-integrated projects is a massive leap.
Since I am just starting out (and balancing my academic studies with coding), I am really looking forward to connecting with and learning from the experienced developers in this amazing community.
I would love to get your insights on a few things:

The Big Leap: What is the one piece of advice you would give to a beginner who wants to transition from "learning syntax" to building complete projects?

Avoiding the Trap: How did you escape "tutorial hell" when you were a beginner?

Resources: Are there any specific beginner-friendly communities, roadmaps, or open-source projects you would recommend?

I am incredibly excited to build in public, share my progress, and grow with all of you. Thanks for reading, and let's connect 🚀

Building a Continuous Terminal Calculator in Python

Asara Khatun — Sat, 04 Jul 2026 04:57:15 +0000

Hello DEV Community 👋

I am currently diving deep into Python, focusing on strengthening my core programming logic. Today, I built a simple yet effective Terminal-Based Calculator.

While a basic calculator is a common beginner project, I wanted to ensure it didn't just run once and abruptly stop. I wanted it to feel like an actual software program.

✨ What I Built

A command-line calculator that performs basic arithmetic operations (Addition, Subtraction, Multiplication, Division) and continuously runs until the user explicitly commands it to stop.

🧠 The Core Logic: The `while` Loop

The game-changer for this project was wrapping the main logic inside an infinite while True: loop. Instead of the terminal closing after one calculation, the program loops back, asking the user for their next operation.

Here is how I structured the workflow:

User Menu: Display options (1 to 5).
Exit Condition: If the user selects '5', a break statement gracefully exits the loop.
Error Handling: Used a try-except block to catch ValueError just in case someone types a letter instead of a number. I also added a condition to prevent ZeroDivisionError.

💻 The Code

Here is the complete code for my calculator:


python
def start_calculator():
    print("--- Python Terminal Calculator ---")

    while True:
        print("\nOperations:")
        print("1. Add (+)")
        print("2. Subtract (-)")
        print("3. Multiply (*)")
        print("4. Divide (/)")
        print("5. Exit")

        choice = input("Select an operation (1/2/3/4/5): ")

        if choice == '5':
            print("Shutting down... Goodbye! 👋")
            break

        if choice in ('1', '2', '3', '4'):
            try:
                num1 = float(input("Enter first number: "))
                num2 = float(input("Enter second number: "))
            except ValueError:
                print("Error! Please enter valid numbers only.")
                continue  

            if choice == '1':
                print(f"Result: {num1} + {num2} = {num1 + num2}")

            elif choice == '2':
                print(f"Result: {num1} - {num2} = {num1 - num2}")

            elif choice == '3':
                print(f"Result: {num1} * {num2} = {num1 * num2}")

            elif choice == '4':
                if num2 != 0:
                    print(f"Result: {num1} / {num2} = {num1 / num2}")
                else:
                    print("Math Error! Cannot divide by zero.")
        else:
            print("Invalid Input! Please select a valid option.")

if __name__ == "__main__":
    start_calculator()

Automating Smart Shopping: I Built an Amazon Product Rate Tracker

Asara Khatun — Thu, 02 Jul 2026 05:09:49 +0000

Hey DEV Community 👋 I’m Asara, a science student and tech enthusiast who loves solving real-world problems. Today, I want to share a recent project I built that tackles something we all experience: trying to catch the best price on Amazon.
💡 The Idea
We all have that one item sitting in our cart, waiting for the price to drop. Constantly refreshing the page is exhausting. I realized I could use my coding skills to automate this, so I built an Amazon Product Rate Shopping tool.
⚙️How It Works
I wanted to keep the user experience as simple as possible.
Input: You simply paste the link of the Amazon product you have your eye on.
Process: The tool verifies the product link in the background.
Output: It tracks and extracts the exact current price of that product directly from the page.
🛠️ The Tech & Logic Behind It
Instead of focusing on heavy frameworks, I put all my energy into core programming logic (utilizing my skills in Python/Java). The primary challenge was ensuring the URL verification was accurate and that the program could reliably parse the data to find the specific price element.
🧠 My Biggest Takeaways
Building this tool taught me so much about data extraction, handling real-world URLs, and the power of automation. There is nothing quite as satisfying as watching your own tool fetch accurate live data for the first time.
I am still exploring and learning every single day. I’d love to hear from this amazing community—have you ever built an automation or tracking tool? What was the hardest part for you?
