python - __init__() 缺少 1 个必需的位置参数 : 'quantity'

Question

我收到问题中显示的错误，但我不明白为什么。即使在尝试其他 Stack Overflow 方法来修复此问题时，它也不起作用。

class Item(object):
    def __init__(self, name, style, quantity):
        self.name = name
        self.style = style
        self.quantity = quantity
    
class Weapon(Item):
    def __init__(self, name, style, quantity=1):
        Item.__init__(name, style, quantity,)

Bow = Weapon(name = "Bow", style = "WRanged", quantity = 1)

受错误代码影响的行:

Traceback (most recent call last):
  File "C:\Stuff\SG\Work\Inventory.py", line 33, in <module>
    Bow = Weapon(name = "Bow", style = "WRanged", quantity = 1)
  File "C:\Stuff\SG\Work\Inventory.py", line 12, in __init__
    Item.__init__(name, style, quantity,)
TypeError: __init__() missing 1 required positional argument: 'quantity'

Answer 1

改变

Item.__init__(name, style, quantity,)

对于

super().__init__(name, style, quantity)
