In Python 2.x you can do s.find(..), s.replace(..), etc. where s is a byte string. This API does not exist anymore in in Python 3.x and you can only do string manipulation if s a unicode string. This is very bad because all network protocols use bytes not unicode. The solution bytes>unicode>manipulate>unicode>bytes does not work because not all ascii data can be represented in unicode (and at least not without a major performance penalty).
Python 3.x is making more difficult to program low level network protocols and it moves the developer away from the OS representation of data.
