动态赋值__setattr__属性用法

动态初始化属性：常用于selenium，可以将定位的元素放到yaml中，然后取出来循环初始化属性

class dt_fz():
    def __init__(self):
        _data = {"name": "zxb", "age": 18, "character": "hopeful"}
        for key  in  _data:
            self.__setattr__(key,_data.get(key)) #相对与self.name = "zxb" ,self."age"=18,self.character="hopeful"


if __name__ == '__main__':
    print(dt_fz().name) #zxb
    print(dt_fz().age)  #18
    print(dt_fz().character) #hopeful
