Python import fails for copied directory
===


I had a directory structure like the following for a Python project:

    my_project
    |_ 
       ... 
       dirA
          |_ 
            __init__.py
            scriptA.py
       dirB
          |_
            __init__.py
            scriptB.py
       ...

Inside `__init__.py` of `dirA` (`__init__.py` of `dirB` is empty), I have:

    import os
    import glob
    __all__ = [os.path.basename(f)[:-3] for f in glob.glob(os.path.dirname(os.path.abspath(__file__)) + "/*.py")]

Inside `scriptB.py`, I do:

    from dirA import *

And the subsequent code which utilizes the imports works fine.

Then, I copied and pasted the whole project (with a different project directory name: `my_project_new`) in the same directory as the old one, and I start changing the code of `scriptA.py` in this newly duplicated directory. (*Note*: directory structure of `my_project_new` remains exactly the same as above).

After making the changes, I tried to run `scriptB.py` of `my_project_new`, and I found that **it kept importing `dirA` from the original `my_project` directory**, instead of the `dirA` in the current `my_project_new` directory. Why is this?

Further, I moved the original `my_project` folder to a different location, and tried to run `scriptB.py` of `my_project_new` again. It then failed to identify `dirA` altogether. What is happening now?
