How do I run python '__main__' program file from bash prompt in Windows10?

I am trying to run a python3 program file and am getting some unexpected behaviors.

I'll start off first with my PATH and env setup configuration. When I run:

which Python

I get:

/c/Program Files/Python36/python

From there, I cd into the directory where my python program is located to prepare to run the program.

Roughly speaking this is how my python program is set up:

import modulesNeeded

print('1st debug statement to show program execution')

# variables declared as needed

def aFunctionNeeded():
    print('2nd debug statement to show fxn exe, never prints')
    ... function logic...

if __name__ == '__main__':
    aFunctionNeeded() # Never gets called

Here is a link to the repository with the code I am working with in case you would like more details as to the implementation. Keep in mind that API keys are not published, but API keys are in local file correctly:

https://github.com/lopezdp/API.Mashups

My question revolves around why my 1st debug statements inside the files are printing to the terminal, but not the 2nd debug statements inside the functions?

This is happening in both of the findRestaurant.py file and the geocode.py file.

I know I have written my if __name__ == '__main__': program entry point correctly as this is the same exact way I have done it for other programs, but in this case I may be missing something that I am not noticing.

If this is my output when I run my program in my bash terminal:

$ python findRestaurant.py
inside geo
inside find

then, why does it appear that my aFunctionNeeded() method shown in my pseudo code is not being called from the main?

Why do both programs seem to fail immediately after the first debug statements are printed to the terminal?
