    def bar(self):
        self.__foo()  # self._Teacher__foo


p1  =  Person("xi",22)
p1.get_name() #xi
p1.__foo() # foo
p1._Person__foo() # foo
p1.bar() # Teacher无__foo变量 (AttributeError: 'Person' object has no attribute 'bar')


t1 = Teacher("xi", 23)
t1.bar() # Teacher无__foo变量 (AttributeError: 'Teacher' object has no attribute '_Teacher__foo')
