Always post actual tracebacks of the problem, if
indeed it is producing a traceback.  Do this always
by *cut and paste*, not by retyping the text.  Make
sure not to remove anything important, and make sure
you are running the actual code you have posted here.

Also always describe the problem in more detail than
just "doesn't work".  For all we know, the code runs
fine but its output just doesn't suit you...
