I have a simple piece of code. In it I make 2 animals a cat and a spider. They have a difference number of legs and eyes. I just want to print these data.

class Legs:
    def __init__(self, amount):
        self.amount = amount  

    def legsInfo(self):
        return f"{self.amount} legs"


class Eyes:
    def __init__(self, amount):
        self.amount = amount  

    def eyesInfo(self):
        return f"{self.amount} eyes"


class Animal(Legs, Eyes):
    def __init__(self, name, legs_amount, eyes_amount):
        self.name = name
        Legs.__init__(self, legs_amount)  
        Eyes.__init__(self, eyes_amount)  

    def legsInfo(self):
        return super().legsInfo()

    def eyesInfo(self):
        return super().eyesInfo()


# Objects
cat = Animal("Tom", 4, 2)  
spider = Animal("Webster", 8, 6) 

# Test de output
print(cat.legsInfo())     # 2 legs ERROR
print(cat.eyesInfo())     # 2 eyes
print(spider.legsInfo())  # 6 legs ERROR
print(spider.eyesInfo())  # 6 eyes

It appears that because of the property amount is used in both classes, this value is shared. Which I think is very strange, it are different classes, so there is no need to share.

Is this a Python bug or some kind of “special feature”?

I have changed the name amount to legsAmount and eyesAmount and then it works fine. I want to define / specify / set the amount variable as “only for this class” or something.
