Import and variable level

[tazalapizza]

Hi, I am working with a few friends on a project where everyone makes some functions that have to use the same variables, for example x here. Every function will be imported in a main.py file and then use x, which is created in main.py. We thought that it would not be necessary to put x as an argument of every function because x would be a global variable, but it seems like it is not. Is there a solution to make this work, other than storing every variables in a file and importing this file everywhere ? Or is there a cleaner way to use our functions together ? We would like to avoid putting the variables as arguments of the functions because there is a lot of them.
Example:

#secondary.py
def function():
    print("secondary:", x)


#main.py
from secondary import function
x=0
function()

I get

Error:
NameError: name 'x' is not defined

and I want to print "secondary: 0"

you need to pass x as an argument:

#secondary.py
def function(x):
    print("secondary:", x)
 
 
#main.py
from secondary import function
x=0
function(x)

Also, be aware that you set x to 0 prior to running function
