python的父類和子類的繼承關係和super()的使用

子類繼承父類的私有方法重寫無效，公有方法可以重寫，引用父類方法可用super()實現

class A(object):
    def __init__(self):
        self.__private()
        self.public()
    def __private(self):
        print('i am a private method in A')
    def public(self):
        print("i am a public method in A")
class B(A):
    def __private(self):
        print("i am a private method in B")
    def public(self):
        print("i am a public method in B")
    def superMethod(self):
        super().public()
print("父類（基類、超類）".center(60, '-'))
a=A()
print("子類（派生類）".center(60, '-'))
b=B()
b.superMethod()
