How to determine the default start file in vim given the file extension?

Question

Every time I write a new python program, I find the same starting lines again and again:

#!/usr/bin/env python
'''
Description of the program
'''
import always, the, same, libraries

def helper_function(helpers_args):
'''
A function that is called in get_main_output, but that someone might want to import too.
'''
    continue

def get_main_output(program_arguments):
'''
Description of the main function
'''
    continue

if __name__ == '__main__':
    output = get_main_output(sys.argv)

I do not want to do this manually every time. I would like vim to show me this file every time I open a nonexistent file with the extension .py, so I can modify it as needed, and then save it in the newly created source file.

How can i achieve this?

Apologizes if the answer is already somewhere. I thought it would be, but I could not find it anywhere.

~/.vim/skeleton.py

Put the python code from your source message inside this file as a simple custom
