当在另一个函数中用作参数时，如何将自定义Python对象表示为字符串？

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

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

person = Person("Alice", 25)
print(str(person))  # 输出：Person(name=Alice, age=25)

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})"

person = Person("Alice", 25)
print(repr(person))  # 输出：Person(name=Alice, age=25)
