[New-bugs-announce] [issue40443] Remove unused imports in the stdlib (April 2020 edition)

[STINNER Victor]

New submission from STINNER Victor <vstinner at python.org>:

Attached PRs removed unused imports from the Python standard library.

I used pyflakes and looked for "imported but unused" warnings. I ignored tons of warnings, since many are false alarms: imports done on purpose.
