Python global dict across different file script

Hello. I am trying to use a global dict created in main.py, which is called in functions.py. In my main.py I have:

import sys,os,...
import functions.py #import my second file

matrix = {}
matrix_do_something
search_the_matrix(value) #which is defined in functions.py

#FILE: functions.py
def search_the_matrix(value):
    global matrix
    if value in matrix:
        return True
    else:
        return False

and I get this error:

NameError: global name 'matrix' is not defined

I have read a solution on stackoverflow, which says to put everything in a global file and then call from every file global.matrix[value] but I don't want this. I want just call it matrix and think of it as my global matrix. Is this possible? Thank you in advance

In functions.py you would have to import it 

from main import matrix

Though I would want to come up with a better name for my module than main.

If you want an object to be available in a module / file you need to either create it there or import it from somewhere else.
