I think I can understand the sentiment here.
However, I would prefer a str.replace_all method that would accept it. I
cannot think of any place, where I would want to use either a str or a
list of str. So, this could hide bugs.
Speaking of "replace", sometimes, I would love to pass an "replace all
of these with all of those" dict, which is then processed internally. I
can remember two times where we needed to write some kind of for-loop;
which actually might produce wrong results:
convert_dict = {
'1': '2',
'2': '3',
}
original = '12345'
for from_, to in convert_dict.items():
original = original.replace(from_, to)
Real-world examples don't really have this issue so we accepted this
kind of workaround for smaller scripts. But I would prefer a stdlib
solution for this.
Best,
Sven
