Using import our script with Python

Question

I don't know how explain what I want do so I think with code example you can understand.

y.py

y = 0

import printy

printy.py

import y

print y

NameError: name 'y' is not defined

When I call scripts with import works perfect but I want to know how I can share variables.

y.py

import printy

printy.py

y = 0

print y

result = 0

try: import printy; print printy.y or from printy import y; print y. — hiro protagonist

It's generally not a good idea to have two modules that import each other, so try to avoid that if you can. Do a search for "circular imports" for more info. — PM 2Ring

I don't know which is which file, (assuming each code block is a different file) it should work, and share variables if importing them works. Also, I would write it like this:

file y.py:

from printy import *

y = 0

file printy.py:

from y import *

print y

Also, both files have to already exist at time of running, and they have to saved into the same folder.

EDIT: If result = 0 is the output, then everything is working fine. Also, if this doesn't work, I'd do printy.print(y)

Also, if you want to do more complex code, it will work best to save the code, in file being retrieved, in a function.
