The problem is your use of input()
It reads the blank line you type and tries to evaluate it, 
which it can't do.

Use raw_input instead, it simply assigns the string 
(to nothing in this case) without attempting to evaluate it.

Try using the interactive prompt to see the same thing:

>>> input()
<-- 
Traceback (most recent call last):
  File "<input>", line 1, in ?
  File "<string>", line 0
    
    ^
SyntaxError: unexpected EOF while parsing
>>> raw_input()
<-- 
'\n'
>>>
