【604】Python class __dict__.update的使用
作者:互联网
参考:python中dict.update与__dict__的使用
可以通过 __dict__.update() 批量构建类的属性
可以类内字典:
class Person(object): _defaults = { "name" : "alex", "age" : 18, "city" : "Sydney" } def __init__(self): self.__dict__.update(self._defaults) def printName(self): print(self.name) def printAge(self): print(self.age)
也可以类外字典:
dicts = { "name" : "alex", "age" : 18, "city" : "Sydney" } class Person1(): def __init__(self): self.__dict__.update(dicts) def printName(self): print(self.name) def printAge(self): print(self.age)
相当于:
dicts = { "name" : "alex", "age" : 18, "city" : "Sydney" } class Person2(): def __init__(self): self.name = dicts["name"] self.age = dicts["age"] def printName(self): print(self.name) def printAge(self): print(self.age)
