I know what happened. You just run this module, and you thought that you start running it from the main function (like in C for example). There is no problem with the raw_input line (the first line of the input). The problem is that your module does not try to read anything! You just typed "1 1 1 1 1" which is of course syntax error...
Append to your code this line to run the main function:
main()
You can also write the code of the main function not in some function, to get the same effect.
