Introduction π
Every programming journey begins with a simple yet powerful tradition β printing "Hello, World!" to the screen. Itβs the easiest way to learn how a language works, verify installation, and understand basic syntax.
Note
1. Create a Python File π
Open your code editor (VS Code recommended), and create a new file named:
Code Snippet
hello.pyThis file will contain the Python code youβre about to write.
2. Write the Hello World Program βοΈ
Inside hello.py, type the following line. This uses Pythonβs built-in print() function to display text.
hello.py
print("Hello, World!")3. Run the Program βΆοΈ
Open your terminal and navigate to the folder containing hello.py.
Code Snippet
python hello.pyOnce executed, you should see:
Code Snippet
Hello, World!π Congratulations β youβve officially written your first Python program!
4. How It Works π§
- print() β A function used to output text to the console.
- "Hello, World!" β A string (a piece of text inside quotes).
- Python automatically handles the printing β no semicolons required! π
5. Common Mistakes β οΈ
- Using wrong quotes: always use " " or ' '
- Spacing issues are rare here, but important later in Python.
- Using Print instead of print β Python is case-sensitive.
6. Experiment More π¨
Try modifying the message to understand how strings work:
experiment.py
print("Hello, Sathish!")
print("Welcome to Python!")Make Python talk to you however you want! π
