Python: Unable to import class from another file in different directory

Question

I have following directory structure: ProjectRoot is root project directory. It contains directory 'a' which has mypython.py, which in turn contains a class MyPython. At same level as 'a', there is another directory 'b', which contains file named another.py.

I am trying to import MyPython class in another.py as:

from a.mypython import MyPython

But during execution this gives error as:

ModuleNotFoundError: No module named 'a'

I event tried to put __init__.py' in a as suggested by many, but still no success.

How to get it working? Its Python 3.7.

Answer 1

If you're doing python b/another.py , this cannot work. Please try python -m b.another instead (after touch a/__init__.py ).
