You have illegal characters on line 10 or the end of line 9. These most likely came from copying and pasting. The easiest way to correct the problem is to retype (do not copy and paste, and don't use and keyboard macros like shift-space) line 10 and line 9 if required.
As for tutorials certainly your Google foo is as good as anyone elses here. You may also want to look at the Python code which may be clearer.
