List not defined when importing a function

Question

I made two modules in Python. The other one is a sentinel-controlled loop that asks for the data and the other module contains the functions needed for computation. When I import Module 2 (module with functions), I get a Name Error.

NameError: name 'x' is not defined

where x is the argument of my function convert(x)

but x is a defined list in Module 1 (sentinel-controlled loop) where I store data. I can't figure out why the imported module does not consider it.

I imported the other module as

import ModuleName

What could be the problem?

Disclaimer: I'm a beginner in Python so I'm not really very familiar with it.

Answer 1

It has to do with the way you import. There are a couple of ways to resolve this.

In the example below, you import module_name and then call function x in the proper namespace.

import module_name

module_name.x()

Another way would be to explicitly import function x from module_name.

from module_name import x

x()

I highly advise you to do some reading on how importing works in python, w3schools is always a good starting point.
