No, but you can use pychecker to get similar results.

Not really.  Forced variable initialization is what's important.
Unlike C, et al, and Perl, variables don't have a default 
initial value.  If you try reference a variable that hasn't been
initialized ("bound to a value", in python lingo), python raises a
NameError exception.

    --dang
p.s.
I know technically Perl initializes to 'undef', but it's magically
treated as 0 or an empty string, depending on context, so the
effect is much the same.
