Setting Up Python

This lesson walks through installing Python and running your first program. Replace this with your own content.

Installing Python

brew install python

sudo apt install python3

Your first program

Create a file named main.py:

def main():
    print("Hello, Python!")
if __name__ == "__main__":
    main()

Run it from the same folder:

python3 main.py

The terminal prints Hello, Python!. On Windows, run py main.py instead.
