class rectangle:
    def __init__(self, length, width):
        self.length = length
        self.width = width
    def s(self):
        return length * width
class square(rectangle):
    def __init__(self, length):
        self.length = length
        self.width = length
a = square(5, 5)
print(a.s)

这段代码有什么问题呢？

class rectangle:
    def __init__(self, length, width):
        self.length = length
        self.width = width

    def s(self):
        return self.length * self.width  #少了两个self


class square(rectangle):
    def __init__(self, length, width): #少了width参数
        self.length = length
        self.width = length


a = square(5, 5)
print(a.s())   # 方法调用少了括号

修改一下：

class rectangle:
    def __init__(self, length, width):
        self.length = length
        self.width = width
    def s(self):
        return self.length * self.width
class square(rectangle):
    def __init__(self, length):
        self.length = length
        self.width = length
a = square(5)
print(a.s())
