如何把变量的值变为self.obj其中的obj的名字?

You can use method __getattribute__ for attributes of an object.

class Example():

    def __init__(self):
        self.a = 100
        self.b = 'book'
        self.c = ('Jason', 'Yang')

    def go(self):
        pass

e = Example()
print(e.__dict__)

for text in e.__dict__:
    print(e.__getattribute__(text))

{'a': 100, 'b': 'book', 'c': ('Jason', 'Yang')}
100
book
('Jason', 'Yang')

谢谢!
