Explane how can you make a Python Script executable on Unix?

 To make a Python script executable on Unix, you need to add a shebang line at the beginning of the script, which tells the system what interpreter to use to run the script. The shebang line should be in the following format:

#!/usr/bin/env python3

Next, you need to make the script file executable by running the following command in the terminal:

chmod +x script.py

This allows the file to be executed as a program. You can now run the script by typing ./script.py in the terminal.
