Encountering an Error with Python 3.13's wave Module

Hey everyone, I've been working with the wave module in Python 3.13 and ran into a strange error. I was generating a simple sine wave and saving it as a WAV file using the built-in wave module. My code is pretty standard, using wave.open() within a with statement for file handling. However, at the end of my script, I get this error during the cleanup phase: `wave.Error: # channels not specified`. I've set the channels correctly with `wav_file.setnchannels(1)`, so it feels like the issue might be internal to the library when closing the file. Has anyone encountered this or know if it's a known bug in this version? Thanks!

It turns out there wasnโ€™t a bug in the wave module; it was a typo in my code. I mistakenly typed "get" instead of "set" for the channels! Got a bit overconfident there, my bad!

I doubt you found a bug; it doesn't seem like a cleanup error. You might want to double-check your code for small mistakes.

Could you share your full script? It would help to test it more accurately. Also, any details on your project structure would be useful since we want to rule out any namespace issues.
