Problems with user input

That's because your terminal is in canonical mode - that means that it only
reads whole lines. You can put it to non-canonical mode - one way is
described here:

Please make sure you set it back to canonical mode, or you will expirience
some strange effects.

The print statement concats an argument list by spaces. Use this instead:

sys.stdout.write("Your input:%s\n" % input)
