No module named “code.X”; code is not a package, Python

Question

I have the following project structure:

Project
|
---code
|  |
|  ---__init__.py
|  ---X.py
|  ---Y.py
|  ---Z.py
|
----resources
    |
    ---__init__.py
    ---csv/
         |
         --- file1.csv
         --- file2.csv
         ---__init__.py 

Inside X.py and Y.py I have an import from code.Z import Z (where Z is the name of the class inside, and also a filename. When I want to run Z.py, it gives: `ModuleNotFoundError: No module named 'code.Z'; 'code' is not a package.

What's wrong?

Answer 1

There are two possible problems here:

1. make sure Project is on the python path, otherwise it cannot find code
2. code is an internal module in the python standard library which might cause name clashes, see https://docs.python.org/2/library/code.html . To avoid this, change the folder name to src, or anything else but code.
