Here's the essence of your program:

print(repr(raw_input()))

You can use that to verify what's going on. Try running that with and
without the -u option; note, by the way, that -u actually means
"unbuffered", not "flush buffers".

You're running this under Windows. The convention on Windows is for
end-of-line to be signalled with \r\n, but the convention inside
Python is to use just \n. With the normal use of buffered and parsed
input, this is all handled for you; with unbuffered input, that
translation also seems to be disabled, so your string actually
contains '120\r', as will be revealed by its repr().

By the way, raw_input() already returns a string. There's no need to
str() it. :)
