First things first. what operating system are you using,  and
 where did you get the mysterious graphics. py?  Thanks for
 telling us python 2.7.3

Next, please repost any source code with indentation preserved. 
 Your message shows it all flushed to the left margin,  probably
 due to posting in html mode. Use text mode here.

Finally,  since you seem to be using googlegroups,  please make
 sure you don't double space your quotes. See. wiki.python.org/moi
