Local Python Module imports when using virtualenv

Importing modules in python3 can be unnecessarily confusing, especially when using virtualenv

Suppose you have this file structure:

.env
test.py
cool_modules
    |--__init__.py
    |--cool_module1.py
    |--cool_module2.py
Enter fullscreen mode Exit fullscreen mode

To prevent import errors while using virtualenv .env:

cool_module1.py:

class CoolModule1():
    ...
Enter fullscreen mode Exit fullscreen mode

cool_module2.py:

class CoolModule2():
    ...
Enter fullscreen mode Exit fullscreen mode

Here's the critical part.
init.py:

# The part to note here is you have to use `parent_folder.child_file`
from cool_modules.cool_module1 import CoolModule1
from cool_modules.cool_module2 import CoolModule2
Enter fullscreen mode Exit fullscreen mode

test.py:

from cool_modules import CoolModule1, CoolModule2
Enter fullscreen mode Exit fullscreen mode

That's it!
