misc: Update Python syntax

[kingiler]

As we are using latest two Python versions, many code written years before can be upgrade to use the newest syntax for readability and performance. Since the upgrade is huge, I propose to upgrade in phrase by a series of PRs.

• Upgrade to Python 3.8+
  • Redundant r mode in open python: Remove redundant r mode in open #1249
  • Use f-string instead of .format or % python: Use f-string #1251
  • Use generator, or direct syntax. python: Use generators or direct syntax #1252
  • Update typing hint
• Upgrade to Python 3.9+
  • PEP 585 typing rewrites (https://peps.python.org/pep-0585/)
• Upgrade to Python 3.10+
  • PEP 604 typing rewrites (https://peps.python.org/pep-0604/)

In general, I'm fine with this, I just don't see the pressing need for this, unless we're doing a "lint party" or similar. I prefer doing that once the code is touched in the course of other feature-rich PRs. Lastly, for these kind of issues/PRs, I'd prefer kicking off a discussion on Zulip maybe first.

I agree, I'm a big fan of these changes iff all other functional work is blocked in one way or another.
