remove all bare excepts and trailing whitespace

[hutch3232]

If there is no objection, I'd like to eventually setup ruff linting for this project (I'll open an issue). Before that happens, a few unobjectionable (imo) changes would be to remove bare excepts and trailing whitespace (and ensure files end with one newline).

• https://docs.astral.sh/ruff/rules/#warning-w
• https://docs.astral.sh/ruff/rules/bare-except/

A lot of whitespace changes - easier to view if you use GitHub button to hide whitespace in the diff.

I think the last time that this was brought up is that the group does not want to use a linter for this project. If you are making changes to codes and want to use a linter to clean up your PR that's ok, but we do not want to choose one linter to go with for the whole project.

I'd suggest that this PR be withdrawn for now. Would you like to bring this up to the group again?
