This should be f = iter(raw_input,"") and this will end in a EOFError and stop 
on blank line.
So you need a wrapper like :

>>> def stdin_iterator() :
...     while(True) :
...         try : yield raw_input()
...         except EOFError : return
...
>>> f = stdin_iterator()

Do you really need to iterate on the file this way instead of using the 
straightforward readline method ?

>>> import sys
>>> l=sys.stdin.readline()

>>> while(l) :
...     print l,
...     l=sys.stdin.readline()
