you can get the none type with None.__class__ or with the 'types' module, but 
it won't work as the except handler only accepts Exception classes. It sounds 
like you're confusing with some other error, what is the exact message of 
your 'NoneType error' ? The exception type you want to catch should be at the 
beginning of it (as in 'TypeError: blah blah...')
