Unfortunately no, but I have now pushed python3-3.8.14-1.1.mga8 to core/udpates_testing to also include fix for bug 30572. python-pip is updated to match bundled pip version in updated python3.

MGA8-64 MATE on Acer Aspire 5253
No installation issues
Testing according wiki
$ python3 /usr/share/doc/python3-ply/example/calc/calc.py 
WARNING: Couldn't open 'parser.out'. [Errno 13] Permission denied: '/usr/share/doc/python3-ply/example/calc/parser.out'

WARNING: Couldn't create 'parsetab'. [Errno 13] Permission denied: '/usr/share/doc/python3-ply/example/calc/parsetab.py'
calc > a=5
calc > b=6
calc > a*b

exit with CTRL-D
On the warnings:
first one: the referenced file does not exist
second: indeed no write-acess on this folder.
The update seems to function OK, but leaving others to judge on this warnings.

Comment 12 Len Lawrence 2022-10-05 19:15:59 CEST 
Tried the test as root and as expected it worked without the parsetab error message.  
$ sudo python /usr/share/doc/python3-ply/example/calc/calc.
Generating LALR tables
calc >
....

As it does not seem to need parsetab when run as a user just ignore it and give the OK.
