It's very simple: The input() function in Python 2.x is a very
dangerous one - it's equivalent to eval(input()) in Python 3. The
equivalent function in Python 2 is called raw_input. For safety and
compatibility, just do this at the beginning of your interactive
session or the top of your script:
input = raw_input
or, in a way that'll work in Python 3 as well, with no changes:
try:
input = raw_input
except NameError:
pass
After that, you can safely call input() and get back a string.
