Hi Alan.
You are correct with the indentation.
class Cat:
name = ""
kind = "cat"
color = ""
value = 100.00
def description(self):
desc_str = "%s is a %s %s cat worth R%.2f." % (self.name,
self.color, self.kind, self.value)
return desc_str
The above code is the question, which I am not allowed to edit.
So just to test the lecturer's code, I run the command
print(Cat.description())
This returns an error.
>>>> TypeError: description() missing 1 required positional argument: 'self'
To me, this is flawed. I should be able to get a fault less response from
that command.
Any other code I append to it by inheriting the class Cat, will still have
that similar error.
Now, I've added the following code to inherit the class Cat: description.
class Cat1(Cat):
name = "Whiskers"
kind = "Burmese cat"
color = "grey"
value = 3000.00
When I run this command, I still receive the same error.
print(Cat1.description())
Please assist where possible.
Regards
Vusa
