I don't know enough about proper Python usage to submit doc patches, so 
when I google and can't find an answer and none of my coworkers can 
answer my question, I post here for help... I wouldn't call that 
whining, but you're entitled to your opinion of my post.

If I were knowledgeable enough to submit doc pathces, I would do so.

Thank you,

Brad
