Playing with Mixin which is basically a multiple inheritance. I was confused before on what the line 'cls = TestMixin' does ..

test_mixin.py

class TestMixin(object):
	member1 = ['gant','from','mixin']

	def mixin_method(self):
		print 'member 1 from self: %s' % self.member1
		cls = TestMixin
		print 'member 1 from cls: %s' % cls.member1

class Cat(TestMixin):
	member1 = 'meow meow'

	def bark(self):
		print 'I bark %s' % self.member1

if __name__ == '__main__':
	a = Cat()
	a.bark()
	a.mixin_method()
