[Tutor] String question

[orbitz]

For starters, you don't need to import string. string.split(line) can be 
done with line.split().  line is of type str, which is a built in and 
contains most of the string members.  import string is only necessary 
rarely.

Secondly I could be wrong, but I don't think you have given enough code 
to really fix the problem.  Your error says it's on line 0, but your 
input() in what you pasted is definitely not.  My guess is you have 
indented someplace you shouldn't, or vice versa, or you have missed a " 
or something like that.

Good luck
