Append items to list in another file - Python

Question

I'm trying to append inputs to a list in another python file. I think I have the order correct but the error message I get is AttributeError: module 'inventory' has no attribute 'pick' when I try it out.

main.py:

import inventory

choice = input("--> ")

if "inv pick" in choice:
    inventory.pick()

inventory.py:

import main

backpack = []

def pick():
    """
    Function for picking up things
    """
    backpack.append(main.choice)
    print(backpack)

If I make write the string "inv pick flower" end hit enter I get the error message instead of the printed content of the list 'Backpack'. Maybe I should use .extend instead of .append but neither of it works right now. Any pointers perhaps?

Regards

@MichaelButscher So they can't import each other? Then I have to use a third .py-file to somehow store and process? — Thomas Bengtsson

@IrfanuddinShafi It worked insofar as there are no error messages but nothing gets printed though... — Thomas Bengtsson

Why don't you use the choice as a parameter for pick()? As it is, it's bad design. — Matthias

The following is a much better way to implement what you're trying to achieve without any problematic circular imports.

main.py:

import inventory

choice = input("--> ")


inventory.pick(choice)

inventory.py:

backpack = []

def pick(choice):

    backpack.append(choice)
    print(backpack)
