是否有像集合这样的字典可以使用其值的属性作为键？

class Person:
    def __init__(self, name, age):
        self.name = name
        self.age = age

people = [Person('Alice', 30), Person('Bob', 25), Person('Charlie', 35)]

people_dict = {person.name: person for person in people}

print(people_dict)

{'Alice': <__main__.Person object at 0x7f8a9083c0d0>, 'Bob': <__main__.Person object at 0x7f8a9083c0f0>, 'Charlie': <__main__.Person object at 0x7f8a9083c110>}

person = people_dict['Alice']
print(person.age)  # 输出：30
