Bug in string.lstrip?

[Brian]

Hello - has anyone else had trouble with string.lstrip stripping too
much? Here's what I get (Python 2.3.4):

import string
string.lstrip("test/one/two/a.b.c", "test/one/") 'wo/a.b.c' string.lstrip("test/one/two/a.b.c", "test/one") 'wo/a.b.c' string.lstrip("test/one/two/a.b.c", "test/one/tw") 'a.b.c'

Similar things happened with the strip() string method. Am I missing
something, or should I file a bug report?

Thanks,
Brian

I think lstrip() just removes the characters that are contained in the
second string. The order of characters in the second string is irrelevant.

For example..

"abcdefg".lstrip("bac" )

'defg'

Your examples are correct because it removes a run of any of the
characters contained in the seconds string.

Perhaps someone can explain this better than I can. ;)

'wo/a.b.c'

The second argument of lstrip has a different meaning from what you
think it does --- see the library documentation for the string module
for details.

Strip considers the second parameter as a *set* of characters to
remove.
