I have some code that currently takes four different classes, A, B, C and
D, and subclasses each of them in the same way:
class MyA(A):
def method(self, x):
result = super(MyA, self).method(x)
if result == "spam":
return "spam spam spam"
return result
# many more methods overloaded
class MyB(B):
def method(self, x):
result = super(MyB, self).method(x)
if result == "spam":
return "spam spam spam"
return result
# many more methods overloaded
If that's really what your code is doing - I mean, calling the super()
implementation, checking the result and eventually returning something
else instead - then a simple decorator might be enough... Could even be
"applied" by the metaclass.
