访问作为Python中另一个对象中的数组的对象的属性

class Person:
    def __init__(self, name):
        self.name = name
        self.friends = []

# 创建一些Person对象
alice = Person("Alice")
bob = Person("Bob")
charlie = Person("Charlie")

# 添加朋友关系
alice.friends.append(bob)
alice.friends.append(charlie)

# 访问Alice的朋友的名字
for friend in alice.friends:
    print(friend.name)  # 输出 Bob 和 Charlie

if hasattr(friend, 'name'):
    print(friend.name)
else:
    print("Friend object does not have a 'name' attribute.")

if 0 <= index < len(alice.friends):
    print(alice.friends[index].name)
else:
    print("Index out of range.")
