Pylint isn't useful until you've tailored the messages.  Personally, I 
avoid map, but your usage may vary.  The pylint message that always 
irked me was:

     W0142: Used * or ** magic

"magic"? They're features of the language!  Meanwhile, it doesn't mind 
if you write multiply-inherited metaclasses....
