Explanation of Important Files:
.py files (Python scripts): Contain your Python code. These are the main programs you run. Example: hello.py
.txt files (Text files): Used to store data, configurations, or input/output for your program. Example: data.txt can store names, scores, or any other data your program reads.
requirements.txt: Lists all external Python packages your project depends on. Install them using pip install -r requirements.txt.
Other common files you may encounter:
.csv – Comma-separated data, often used for datasets.
.json – Structured data for APIs or configurations.
.ipynb – Jupyter Notebook files for interactive Python experiments.
Step 5: Run Your First Program
C:\Users\YourName\Desktop> python hello.py Hello, Python!
Enter your name: Alisha Welcome, Alisha
Step 6: Simple Exercise
a = int(input("Enter first number: "))
b = int(input("Enter second number: "))
print("Sum =", a + b)
Enter first number: 5
Enter second number: 7 Sum = 12
