Import modules from different folders

Question

I have following arrangement of files:

python
|---- main.py
|---- files
      |---- folder1
            |---- a.py, a1.py, ...
      |---- folder2
            |---- b.py, b1.py, ...

I wanted to import my modules a.py and b.py to main.py. For this I used the following commands in main.py:

a = 'C:/python/files/folder1'
sys.path.insert(0, a)
from files.folder1 import *

However, I am unable to import modules from folder1 (similarly for folder2).

I get an error:

No module named files.folder1

I cannot use import command as there are many Python files in folder1, folder2, ...

What am I missing here?

Answer 1

Add a file __init__.py (can be blank) to folders files, folder1 and folder2. Then you got a package files with sub-packages folder1 and folder2. After this you can import from the main.py like this:

from files.folder1 import *
