Hey guys,

is the following behaviour expected? I don't really think so...

$ python
Python 3.0.1 (r301:69597, Feb 14 2009, 19:03:52) 
[GCC 4.0.1 (Apple Inc. build 5490)] on darwin

>>> 
>>> 
>>> 
>>> 
>>> s = ' "Peter"'
>>> s
' "Peter"'
>>> s.strip()
'"Peter"'
>>> s.strip('"')
' "Peter'
>>> s.strip('\"')
' "Peter'
>>> s.strip('\"\"')
' "Peter'
>>> 
>>> 
>>> 
>>> s.strip()
'"Peter"'
>>> s.strip().strip('"')
'Peter'
>>> s.strip('"').strip()
'"Peter'

Yes, it is expected.
When you call .strip() without args it strips the whitespaces, when you
call with an arg it strips only what you specified.
In this example:
>>> s.strip('"')
' "Peter'
the left " is not removed because there's a space in between, in this
example:
>>> s.strip().strip('"')
'Peter'
you first remove the space and then the two ".
