It seems like that you're using Python3. If you want to use Python2, change
`input` to `raw_input`. In Python2, `input()` runs user input as code, and
`raw_input()` returns the string. `input()` in Python3 is equivalent to
`raw_input()` in Python2.
On a rather unrelated note, do not put anything in `input()`. Anything in
it is printed out to stdout, and the judge would regard it as a wrong
answer because excess text is received.
