def traet(character_traet):  # 把要执行的模块从这里传进来
        def inner(*args, **kwargs):
            character_traet(*args, **kwargs)  # 调用相应功能
        return inner  #用户调用treat时，只会返回inner的内存地址，下次再调用时加上()才会执行inner函数

@traet
def nurse(nai):
    print("treatment form nurse %s" % nai)

@traet
def monk():
    print("treatment from monk")

def archer():
    print("this is  a archer that can not treat")

monk()

nurse("naiNai")# 这里相当于nurse = traet(nurse)  nurse("naiNai") 你在这里相当于把 nurse这个函数替换了

# 结果:treatment from monk
# treatment form nurse naiNai
