python - 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 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...so on.

Am I missing something here?

Quick Answer:

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 *
