如何按另一个列表对对象列表进行排序

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

    def __repr__(self):
        return f"Person(name={self.name}, age={self.age})"

# 对象列表
people = [
    Person("Alice", 30),
    Person("Bob", 25),
    Person("Charlie", 35),
    Person("David", 20)
]

# 排序依据的列表
order_by_name = ["Bob", "Alice", "David", "Charlie"]

# 按order_by_name列表对people列表进行排序
sorted_people = sorted(people, key=lambda person: order_by_name.index(person.name))

print(sorted_people)

name_to_index = {name: index for index, name in enumerate(order_by_name)}
sorted_people = sorted(people, key=lambda person: name_to_index[person.name])

sorted_people = sorted(people, key=lambda person: name_to_index.get(person.name, float('inf')))
