How to import a module as __main__?

Question

I have a module that has the usual

if __name__ == \'__main__\':
    do stuff...

idiom.

I\'d like to import that from another module

Answer 1

Here is an example of a main module in Python:

#! /usr/bin/env python
import sys
import os

def main(arg1, arg2, arg3):
    print(arg1, arg2, arg3)

if __name__ == "__main__":
    main(*sys.argv)

But you can also include

def main():
   #The module contains Python code specific to the library module, 
   #like tests, and follow the module with this:

if __name__ == "__main__":
    main(*sys.argv)

in any module you would like to run as main.

For example, if you have a library module, you can always use this construct to execute something specific like tests.
