从附近目录而不是站点包中的Python导入模块

Question

I am trying to test changes to a Python module, let's call it my_import_module . Currently, it's in a site package. I would like to import it from my local file structure, not from my site packages.

The folder structure looks like this:

dir
|--dirA
   |--dirB
      |--my_import_file.py
      |--__init__.py
|--dirC
   |--dirD
      |--main.py
      |--__init__.py

I am trying to import the file my_import_file.py into main.py , and not from the site packages version.

Currently I have from ../../dirA.dirB.my_import_file import XYZ . This doesn't work.

I would like to not add __init__.py into each directory.

Two questions:

• How can I import my_import_file.py from the directory instead of from site packages?
• What is the Python code to import my_import_file ?

Answer 1

See https://www.python.org/dev/peps/pep-0328/

The way to do is

from ...dirA.dirB.my_import_file import XYZ
