I can't use Python 3.10

[Larz60+]

python version was 3.1, not 3.1.0 released on 13 February 2009
sane with 3.2 which was released on 20 February 2011

versions beginning with 3.0.0 contained the third division

see: https://www.python.org/doc/versions/

EDIT:
Sorry, you asked about 3.10. I misread.
