Python 以字典值的形式访问对象的属性

Question

假设我有一个像这样的dict:

dict = {'people': [<Bob>], 'animals': [<Frank>]}

Bob 和 Frank 是两个具有属性的对象:

Bob = MethodForCreateAPerson(){          Frank = MethodForCreateAnimals(){
    name = 'Bob',                            name = 'Frank',
    age = 30,                                age = 6,
    sex = 'm'                                sex = 'w'
}                                         }

问题是:

当 Bob 和 Frank 的属性是 dict 的值时，如何访问它们？

换句话说，我需要检查从 dict.values() 返回的对象的属性。

感谢帮助

Answer 1

尚不完全清楚您的结构实际上是什么样子，但如果您的字典中的值是对象列表，那么以下内容将起作用:

people = dict['people'] #  get the people list
bob = people[0] #  the first entry in that list is bob
name_of_bob = bob.name #  access the name of bob

also_name_of_bob = dict['people'][0].name #  does the same but in 1 line

像这样访问人员列表可能不是您希望在代码中执行的操作，您可能希望像这样迭代所有人员:

for person in dict['people']:
    person_name = person.name
    # do something with the person or the name
