Python动态设置实例的属性

Question

我有以下课程：

class Family:
    self.dad = Person("Doug")
    self.mom = Person("Jane")

    self.family_members = [self.dad, self.mom]

    def wrap_family_members(self, wrapper_class):
        for family_member in self.family_members:
            # What do I put here?
            # family_member = wrapper_class(family_member) <- this doesn't work. 
            # family_member is locally scoped within the loop and 
            # so family_member = ... doesn't update the Family instance attribute

            # The behavior I want:
            # self.dad = wrapper_class(self.dad)
            # self.mom = wrapper_class(self.mom)
            # ...
            # But I don't want to manually assign these attributes. I want them to be assigned based on what is currently in the list self.family_members

我在上面的评论中解释了这些问题。包装器类可以是向Person对象添加其他功能或方法的任何类。

您可以使用其他类型的for循环：

for i in range(len(self.family_members)):
    self.family_members[i] = wrapper_class(self.family_members[i])
