Using variables from other python files

Question

I'm having some problems with this:

I have two files: random and random2

random has this:

    import random2
    print(random2.verb_list)
    print(random2.x)

random2 has this:

    verb_list = ['x', 'y', 'z']
    other_list = ['1', '2', '3']
    something_else = False

    def Main():
        global x
        x = 1
        print(verb_list)
    if __name__ == "__main__":
        Main()

It gives me this error when I run random:

AttributeError: module 'random2' has no attribute 'x'

Is there a way so I can call the variable x in random? I have python3

@WayneWerner I've tried that and it works. But what I want to do is change the x value in a function. Is it possible? — luistripa

@Two-BitAlchemist Yup, I searched that and used part of the code, but still, it doesn't help. — luistripa

@luistripa You've got to provide an actual error description if you want help. "I looked at the right way to do it that works for everyone else but it doesn't help me." doesn't do anything for anyone involved. What are you trying to do, what exactly have you tried in order to accomplish it, and what errors, if any, are you getting? — Two-Bit Alchemist

The variable x is not created until the Main() function is run. Importing a module means that __name__ isn't set to __main__, so the function is never executed.

You must execute the Main() function. Put random2.Main() in the file random.py after the import line.

The name random is a very poor name for a module, since it collides with the standard python random module. It can create unexpected side effects.
