Install Python from the official website
Save your code in a file with a `.py` extension
Open a terminal or command prompt
Navigate to the folder containing the script
Run `python script.py`
Use `python3 script.py` if required on your system
Check that Python is installed with `python –version` or `python3 –version`
Make the script executable on Linux or macOS if needed with `chmod +x script.py`
Run the script directly on Linux or macOS with `./script.py` if it has a shebang line
Use an IDE or code editor run button if available
