Your First Python Program
Let’s write and run the classic “Hello, World!” program in Python.
Introduction
Congratulations 🎉 — Python is now installed! The best way to start learning any programming language is to write a simple program. In Python, we’ll begin with the classic: Hello, World!
Step 1: Open the Python Interpreter
On your system, open a terminal or command prompt and type:
python
You should see something like:
Python 3.x.x (default, Aug 2025, ...)
>>>
The >>> is the Python prompt where you can type commands.
Step 2: Type Your First Line
print("Hello, World!")
You should see the output:
Hello, World!
Step 3: Create a Python Script File
Instead of typing commands directly into the interpreter, we usually write code in a file.
- Open a text editor (Notepad, VS Code, Sublime, etc.).
- Type the following code:
print("Hello, World!") - Save the file as
hello.py. - Run it from your terminal:
python hello.py
Output will be:
Hello, World!
Step 4: Try Modifying the Program
Change the message inside the quotes and re-run your program:
print("Hello, Python Learner!")
Expected output:
Hello, Python Learner!
Mini Exercise (2 minutes)
Write a program that prints your name and your favorite hobby. Example:
print("My name is Alex")
print("I love playing guitar")
Expected Output
My name is Alex
I love playing guitar
What’s Next?
You’ve written your first program 🎉. Next, let’s dive into Python syntax and basic rules to understand how code is structured.
