[New-bugs-announce] [issue42032] Setting PYTHONPYCACHEPREFIX using ~ (tilde) creates a "~" folder

[Veronica Olsen]

New submission from Veronica Olsen <jadzia626 at gmail.com>:

On Debian Bullseye (testing):

Setting

export PYTHONPYCACHEPREFIX=~/.pycache

has previously worked. With Python 3.8.6, this still works in practice, when running python code (the pycache is still redirected), but during initialisation, the python3 executable creates an empty folder named "~" in the folder where the python exec or a python script is run.

Changing the environment variable to:

export PYTHONPYCACHEPREFIX=$HOME/.pycache

resolves the issue.

Expansion of ~ is of course a bit fickly in general, but 

I assume this is not intended. Deleting those folders from command line is rather tricky!
