Python Quickstart: Your First Program

Python is an interpreted language, meaning you write Python code in a text file (with a .py extension), and then execute it through the Python interpreter.

Here’s how to run your Python file:

1. Open the Command Prompt (Windows) or Terminal (macOS/Linux).
2. Navigate to the folder where your Python file is saved.
3. Type the following command:

   C:\Users\Your Name>python helloworld.py
   

Let’s write a simple Python program, Hello, World!, in a new file called helloworld.py. You can use any text editor (like Notepad, Sublime Text, or Visual Studio Code) to create this file.

Example: Hello, World! Program

1. Open your text editor and type the following Python code:

2. helloworld.py
   print("Hello, World!")
   

3. Save the file as helloworld.py.

Running Your First Python Program

Now, go back to your Command Prompt or Terminal. Navigate to the folder where you saved helloworld.py. Then run:

C:\Users\Your Name>python helloworld.py

You should see the following output:

Hello, World!

Congratulations!
