python中的反射

import a import sys print(sys.modulse['a'].Alipay) print(a.Alipay) print(getattr(a,'Alipay')) print(getattr(sys.modules['a'],'Alipay'))

1. import sys cat = 'Сa' dog = 'Сb' def pig():     print('Сp') print(getattr(sys.modules['__main__'],'cat')) print(getattr(sys.modules['__main__'],'dog')) getattr(sys.modules['__main__'],'pig')()

2. class Person:     def __init__(self,name,age):         self.name = name         self.age = age     def qqxing(self):         print('qqxing') alex = Person('alex',83) wusir = Person('wusir',74) ret = getattr(alex,'name') print(ret) ret = getattr(wusir,'name') print(set) ret = getattr(wusir,'qqxing') ret()

3. 反射类的静态变量

   class A:     Role = '治疗'     def __init__(self):         pass print(getattr(A,'Role'))#调用静态变量的时候需要用类名加上静态名
