How to import Python files in the other directories?

[Muddy Coder]

Hi Folks,

If I have a python file foo.py in the current directory, I can simply
import it in the way below:

import foo

when a project keeps grow, more and more Python files are created, and
they are also needed to put into different directories. Then, a
problem comes: how to import the Python files residing in the other
directories? Somebody helps me out? Thanks!
