I would like to correct myself immediately on that one: In the Pizza-example
(from yesterday as well) it would be possible to overwrite the default price of
the HawaiianPizza with the merging of bypassed kwargs with the ones from the
call itself. Let us assume that the exemption of the 10$ price for all
HawaiianPizzas would be a Family-sized pizza for 20$:
class Pizza:
def __init__(self, *, size, price):
print("The price of this %s pizza is:", (size, price))
@cooperative
class HawaiianPizza(Pizza):
def __init__(self, *, pineapple="chunked", size=8):
print("This pizza has %s pineapple." % pineapple)
super().__init__(price=10, size=size)
class FamilyHawaiianPizza(HawaiianPizza):
def __init__(self, *, pineapple="chunked"):
super().__init__(price=20, size=20, pineapple=pineapple) #This
would overwrite the price of the HawaiianPizza
But this would not be the real intention of the usage, but just a side effect
of correctly handling a simple diamond-like hierarchy. The reason that bypassed
kwargs should overwrite them is that they come from up the MRO and so obviously
should have priority.
Sorry to spam you all,
Have a nice Sunday! Michael
