Directory without code takes import precedent over .py file

[FoamyGuy]

With these files in the root of CIRCUITPY

fake_lib/
  a_spritesheet.bmp
fake_lib.py

When you do in the REPL:

import fake_lib

It seems to be trying to import the directory. The contents of fake_lib.py are just print("Hello fake_lib.py") and that value never gets printed.

If you change the name of fake_lib/ to something else then run the same import it will execute the code inside of fake_lib.py

In CPython testing the same scenario results in the opposite behavior, the .py file will get executed even when the folder name matches it.

Testing was done on:

Adafruit CircuitPython 10.0.0-beta.3 on 2025-08-29; Adafruit Feather RP2040 with rp2040

But I also noticed this on Fruit Jam, and assume it is on all devices.
