ModuleNotFoundError: import of time halted; None in sys.modules

[BrickSigma]

Hi there. I was trying out some of the example codes from readthedocs, and when trying out the following sound example:

import ev3_dc as ev3
from time import sleep

hugo = ev3.Sound(protocol=ev3.USB, host='00:16:53:54:43:18', volume=20)
hugo.verbosity = 1

hugo.play_sound(
    './ui/DownloadSucces.rsf',
    repeat=False
)

sleep(5)

hugo.stop_sound()

I get the following error:

I'm currently running python 3.9.12 on Windows 10. The version of ev3_dc is 0.9.10.1.

I've seen this error online before, but couldn't find a suitable fix. Here is a relevant issue, https://bugs.python.org/issue31642

However, if I run the code through the VS Code debugger, it runs perfectly fine except for some extra commands output:

Running the code in python's IDLE works as normal though. I tried the code in Sublime Text and got the same error as VS Code. Not too sure what to do now

Thanks in advance.

Hello, your error is thrown, when python shuts down. Part of method del of your Sound object is to delete the temporary directory on your EV3 brick. This fails when it tries to print. Can you please explicitly delete your Sound object by adding a last line: del hugo

Another option, which may help, is to use the with statement: with ev3.Sound(protocol=ev3.USB, host='00:16:53:54:43:18', volume=20) as hugo:

I hope, one of the options helps.

Kind regards, Christoph

Both solutions worked, but the first one outputted a lot more commands than the second, but thanks for the help.

One question though, if the del keyword is required at the end, does that mean python isn't deleting the variable/object itself? Is there a reason behind this?
