None of those are keywords. Keywords are these:

Maybe I misunderstand your complaint, but Python draws a sharp
syntactic distinction between references and assignment targets: the
latter are only ever found to the left of an = in an assignment
statement; the former are never found there. There is no reason why an
editor should be unable to tell the difference.

You should lint your code to get warnings about this (and many other
things) at authorship time. A good editor should also provide some
visual warning when a built-in is shadowed.
