What is a partial class?

The c# partial class has been already explained here so I'll just cover the python part. You can use multiple inheritance to elegantly distribute the definition of a class.

class A_part1:
    def m1(self):
        print "m1"

class A_part2:
    def m2(self):
        print "m2"

class A(A_part1, A_part2):
    pass

a = A()
a.m1()
a.m2()
