Re: Odd strip behavior
strip() removes leading and trailing characters, which is why the 't' in the middle of the string was not removed. To remove the 't' in the middle, str1.replace('t','') is one option.

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.
