[New-bugs-announce] [issue5318] strip, rstrip & lstrip bug

[alexlc]

New submission from alexlc <alc at niebla.co.uk>:

Examples of bad behaviour:

>>> 'abacde'.lstrip('ab')
'cde'
>>> 'abaaacde'.lstrip('ab')
'cde'
>>> 'aabacde'.lstrip('aab')
'cde'
>>> 'abcede'.rstrip( 'de' )
'abc'
>>> 'abacdeaab'.strip('ab')
'cde'

Probably a few more similar to these will fail as well.

I have tested this with a fairly recent 2.5 (maybe 2.53 maybe 2.54), and
with 2.6.1. I have commented this to a friend and he recalls problems
similar to these with lstrip and rstrip a few years ago, so it might
have been an early 2.4 version or a late 2.3.

Thanks.
