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?

When I do this in Python 2.7 I use:

import sys
sys.path.append('C:/python/files/folder1')

import a
import a1

Here’s a hack I built to import all modules in a directory into a dictionary:

import os
import sys

dir_of_interest = 'C:/python/files/folder1'
modules = {}

sys.path.append(dir_of_interest)
for module in os.listdir(dir_of_interest):
    if '.py' in module and '.pyc' not in module:
        current = module.replace('.py', '')
        modules[current] = __import__(current)

I just built it and it’s extremely hacky but it might be more like something you want. So, to access the module you want, instead of saying module_name.thing you would say modules["module_name"].thing
