Python could not identify class in module without parantheses

Question

I just had an odd behavior in python which was that I defined a class in a module, and I tried to import it but the interpreter could not find the class.

# src/AudioBuffer.py
class AudioBuffer:

This could not be imported in a different file as

# src/Recorder.py
from AudioBuffer import AudioBuffer

Why could it not be found?

A picture of the stack trace when trying to import the AudioBuffer module inside a Recorder module

Edit: removed false assumption/conclusion of the problem Edit: Added stack trace

Answer 1

Make sure that you have an empty __init__.py file in the directory. Add a dot before the module name:

from .AudioBuffer import AudioBuffer
