抱歉新手问题,但我对编程很新。我的问题是,当从父类继承更多属性而不是我需要时,如何设置其中一个属性等于另一个属性?下面是一个例子:
class numbers():
def __init__(self, x, y, z):
# x, y and z initialized here
class new_numbers(numbers):
def __init__(self, x, y):
numbers.__init__(self, x, y=x, z)
# what im trying to do is get the y attribute in the subclass to be equal to the x attribute, so that when the user is prompted, they enter the x and z values only.
感谢您的帮助!

你需要这样的东西:
class numbers(object):
def __init__(self,x,y,z):
# numbers initialisation code
class new_numbers(numbers):
def __init__(self,x,z):
super(new_numbers,self).__init__(x,x,z)
# new_numbers initialisation code (if any)

你的意思是这样吗?
class numbers():
def __init__(self, x, y, z):
# x, y and z initialized here
class new_numbers(numbers):
def __init__(self, x, z):
numbers.__init__(self, x, x, z)
在函数/方法调用中的关键字之后,不能使用非关键字参数。
