The exact same thing is true of input() in Python 3. In Python 2,
input() is the same as eval(raw_input()), so don't use it ever [1].
You can happily use input() in Py3, even if you get empty input.
I like to put this at the top of cross-version scripts:
try: input = raw_input
except NameError: pass
Then you can proceed to use input() without worries.

[1] Yes, I'm aware there are times when evalling the user's input is
what you want. In those cases, be explicit and use eval.
