Sure they would, thats so nice about python being a dynamically typed
language - as long as self has that function during runtime it'll work.
And during runtime it does have that function because of subclassing
MyTableView from QTableView+BaseView (unless PyQt4 has a restriction).
Take this example:
class Bar:
def my(self):
self.goup()
class Foo:
def goup(self):
print "Hi", self
class FooBar( Foo, Bar ):
def makeit(self):
print "me:", self
self.my()
f = FooBar()
f.makeit()
It'll just work.

Avoiding code-duplication should only be done with subclassing if the
subclasses "make sense", i.e. if they'd also exist without wanting to
avoid the code-duplication. In other cases the duplicated code should
rather be put into some shared functions or the like.
