Python3 importing files in different directories

Question

application
 ├── app
 │   └── folder
 │       └── file_1.py
 │       └── file_2.py
 └── app2
     └── folder2
         └── file_3.py

I created a file_3 and trying to use classes defined in file_1.

I tried to import using the following method but had an issue because file_1 is importing file_2 which then was raising an error.

import sys
sys.path.append('/.../application/app/folder')
import file_1

How can I import file_1 to file_3 and all the files file_1 is depending on.

Answer 1

I think the answer you are looking for is explained in this article. If I further understand you correctly, file_1is using classes from file_2? So my guess would be, that you also have to import file_2 aswell because the current working directory does not contain a file named file_2.
