Switch from map and filter to list comprehensions and generator expressions (#27198)

Browse source 
One of the complex map + filter + lambda combinations here was causing
pylint to have a rare false positive detecting undefined variables.

Switch to list comprehensions and generator expressions which are
easi(er) to read for humans and do not confuse pylint.
