I use string repetition and concatenation frequently. For example, for
indenting a string I much prefer this:
string = " "*n + string
over something like
string = ''.join([''.join(' ' for __ in range(n)), string])
List repetition, not so often, but I do use list concatenation and even
more so tuple concatenation.
So I disagree that they are "almost never" used, or that they are a
mistake. If we didn't have string `+` and `*`, and list `+`, I would
certainly have to roll my own as functions.
