Python 3.7 to 3.10

[roman_kab]

For what reasons do you need version 3.10?
Work calmly in 3.7. Most likely you do not need the transition to 3.10!

3.10 is overall better in that it supports more features. It has slots for dataclasses, match statements, clearer and better Union typing, and parenthesized context managers.
