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
and so on, for MyC and MyD. There's a lot of duplicated code in there.
What techniques do you suggest for reducing the code duplication? I
thought about some variation of:
names = "MyA MyB MyC MyD".split()
bases = [A, B, C, D]
d = dict-of-overloaded-methods
for name, base in zip(names, bases):
globals()[name] = type(name, [base], d)
but I'm not sure that this is a good approach, or how to inject the right
arguments to super in the dict.
Any suggestions or guidelines?
