i must be missing something obvious

[Skaperen]

i ran into a problem with some big code and minimized it and the problem remained.  but should this be obvious?  did i miss something that should be obvious or is there a glitch in my brain?  what do i need to change to make this work?

import cash
pay()

def pay():
    print('hey')
    return

um... you import cash but call pay rather than cash.pay

[snippsat]

import cash

cash.pay()

Or:

from cash import pay

pay()
