a lot of times I need to replace more than one char into a
string, so I have to do something like
value = "test"
chars = "e"
for c in chars:
value = value.replace(c, "")
A solution could be that "replace" accept a tuple/list of
chars, like that was add into the new 2.5 for startswith.
I don't know, but can be this feature included into a future
python release?
Well, another way of doing it would be
>>> values = "this is a test"
>>> chars = "aeiou"
>>> "".join([c for c in values if c not in chars])
'ths s tst'
If your either your chars is a large set or you're performing this repeatedly with the same set of chars, you might want the speed of membership-testing that one would get from a true set:
>>> charset = set(chars) # do this once for the set
>>> # do the following as many times as you like in loops, etc.
>>> "".join([c for c in values if c not in charset])
'ths s tst'
