Traceback (most recent call last):

TypeError: 'in <string>' requires character as left operand
Is there any woraround for this or what am i doing wrong in 2.2 ?
IIRC, until Python 2.3, __contains__ only accepted strings of length 1. 
 Before Python 2.3, I think you needed to do something like:

py> x = 'Hello world'
py> x.find('Hello') != -1
True
py> x.find('wrld') != -1
False
