Greetings.
The strip() method of strings works from both ends towards the middle.
Is there a simple, built-in way to remove several characters from a
string no matter their location? (besides .replace() ;)
For example:
..strip --'www.example.com'.strip('cmowz.')
'example'
..??? ----- 'www.example.com'.strip('cmowz.')
'exaple'

filter()
>>removeChars = ';j'
filter(lambda c: c not in removeChars, x)
'asdfklasdfkl'
>>>
or
a list comprehension
x="asdfjkl;asdfjkl;"
>>''.join([c for c in x if c not in ';'])
'asdfjklasdfjkl'

>>identity = "".join(map(chr, range(256)))
'www.example.com'.translate(identity, 'cmowz.')

And in Py2.6, you'll be able to simplify further:
>>'abcde'.translate(None, 'bd')
'ace'

Or
identity = string.maketrans('', '')
