Calling variables from other directories

[complete_NOOB_91]

Hi guys,
I am having some trouble with calling variables from other directories, the code that I have produced is quite modular so that it is easy to read and follow. But now after testing that each piece of code works separately I now need to make these different codes operate together. Can someone please advise as I am fairly new to the Raspberry pi, also i am programming in python. Thanks

To use code in a modular way in python you would import another module.

Code: Select all

import my_other_module

If is in another folder relative to top level function then you might use

Code: Select all

import folder_name.module_name

Code: Select all

from folder_name.module_name import class_or_function

Have a look at these pages

Code: Select all

from file_name import function_name

I think that's what you're looking for, right?

so...

Code: Select all

from functions import addition

answer = addition(a,b)

a and b are sent over to the function in another file, added together and sent back. simples!
