input() in Python2 evaluated the string and was thus unsafe. On Python2, the right choice is raw_input. In Python3, input does what raw_input did. Work around this. The main "problem" is that lgtm.com flags this as error. The fix in the example is not important, but getting a low number of warnings is.
