Correct Mixin Example

class Base(object):
    def methodX(self):
        print "methodX from Base"
    def methodY(self):
        print "methodY from Base"

class BaseDeriv(Base): #inherits methodX
    def methodY(self): #overrides methodY
        print "methodY BaseDeriv Override"

class Mixin(object):
    def methodX(self):
        print "methodX Mixin Override"

class ExampleClass(Mixin,BaseDeriv): #this is the correct order

        Base.methodX(self)
    def methodsY(self):
        Base.methodY(self)
        BaseDeriv.methodY(self)
        self.methodY() #same as above in this case
