Module not found in python

Question

I have directory structure like the following:

MainDir --FooBar --foobar.py, __init__.py
 |
 Ltests -- foobartest.py, __init__.py

Inside foobartest.py, I am importing

from FooBar.foobar.func_in_foobar import *

__init__.py in foobar contains from .foobar import *

And the init.py is empty in tests folder

But when I try to run the foobartest I get this error

No module named FooBar.foobar.func_in_foobar

• mortymacs: you can make a main file like main.py in MainDir that can access to all directories.
• dm03514: for tests i have found success in making my tests dependent on my python project, and using setuptools development mode to put in on path correctly pythonhosted.org/setuptools/setuptools.html#development-mode stackoverflow.com/a/18884727/594589

I think you can solve this problem the same way as in the answer by Sorin here - https://stackoverflow.com/a/6098238/1491900:

import os, sys, inspect
 # realpath() with make your script run, even if you symlink it :)
 cmd_folder = os.path.realpath(os.path.abspath(os.path.split(inspect.getfile( inspect.currentframe() ))[0]))
 if cmd_folder not in sys.path:
 sys.path.insert(0, cmd_folder)
 # use this if you want to include modules from a subforder
 cmd_subfolder = os.path.realpath(os.path.abspath(os.path.join(os.path.split(inspect.getfile( inspect.currentframe() ))[0],"subfolder")))
 if cmd_subfolder not in sys.path:
 sys.path.insert(0, cmd_subfolder)
 # Info:
 # cmd_folder = os.path.dirname(os.path.abspath(__file__)) # DO NOT USE __file__ !!!
 # __file__ fails if script is called in different ways on Windows
 # __file__ fails if someone does os.chdir() before
 # sys.argv[0] also fails because it doesn't not always contains the path
