This is not odd behavior, you just do not understand what
strip does. :)

The behavior is listed on the API. I highly recommend you 
take time to become familiar with it. 


http://docs.python.org/library/stdtypes.html#string-methods
str.strip([chars])
    Return a copy of the string with the leading and trailing characters removed. The chars argument is a string specifying the set of characters to be removed. If omitted or None, the chars argument defaults to removing whitespace. The chars argument is not a prefix or suffix; rather, all combinations of its values are stripped:
    >>>
    >>> '   spacious   '.strip()
    'spacious'
    >>> 'www.example.com'.strip('cmowz.')
    'example'


    Changed in version 2.2.2: Support for the chars argument.
