How to load submodule dynamically

Question

I setup this complex structure to load submodules dynamically:

Main.py
src \ Clean.py
Source \ Amazon \ Clean.py
Source \ Google \ Clean.py
Source \ Amazon \ __init__.py
Source \ Google \ __init__.py

My src \ Clean.py look like this:

import importlib
Vendors = ["Amazon","Google"]
def Run(Config):
    results = ""
    for vendor in Vendors:
        mod = importlib.import_module("source."+vendor)
        results += mod.Run()
    return results

My __init__.py look like this:

__all__ = ["clean"]

My source>>amazon>>clean.py look like this:

def Run():
    return "Amazon Clean Test"

When I call src \ clean.py, I get this error:

AttributeError: module 'source.Amazon' has no attribute 'Run'

I am calling the whole thing in Main.py:

import src.clean as Clean
result = Clean.Run(Config)

I guess it couldn't load the module in source \ amazon \ clean.py? How do I load that?

Stacktrace:

File "main.py", line 2, in clean
  result = Clean.Run(Config)
File "src\clean.py", line 7, in Run
  results += mod.Run()
AttributeError: module 'source.Amazon' has no attribute 'Run'

Got it to work!

In src \ clean.py, change it dynamic import line to this:

    mod = importlib.import_module("source."+vendor+".clean")

Delete __init__.py

That's it!
