1. I'm using the code below and it works well.
I'm able to select my choices but I can't figure out how to access the choices so I can use the information.
I've tried to run pprint(m_g) but it gives me the error "object is not callable"
if I try to print it with an attribute such as m_g.result it tells me it has no attributes.

def get_m_g(_):
    return [
        "L",
        "G",
        "B",
        "C",
        "S",
        "B",
        "T",
        "Co",
        "Car",
    ]

def main():
    m_g = inquirer.checkbox(
        message="\nChoose the m g:",
        choices=get_m_g,
        validate=lambda result: len(result) > 0 and len(result) <= 2, 
        invalid_message="should be at least 1 m g and no more then 2",
        instruction="(\nselect up to 2 m g)",
    ).execute()

2. can someone explain what is going on here.

if __name__ == "__main__":
      main()

Please use bbtags to hold formatting when posting code.
What is inquirer?

Sorry for not using the bbtags been so long I had forgotten the protocols.
Is there a specific way that we post links as well?

Here is the documentation.

These are not usable error messages. Normally Python prints a long error message called an exception traceback. This long error message gives a lot of information about the issue. Please post Python's complete error messages.

It means that you tried to use the pprint module instead of the pprint function. You can do

pprint.pprint(m_g)

Or alternately you could replace

import pprint

by

from pprint import pprint
