如何检查数组中是否已经存在自定义对象？

class CustomObject:
    def __init__(self, name):
        self.name = name

# 示例自定义对象
obj1 = CustomObject("Object 1")
obj2 = CustomObject("Object 2")
obj3 = CustomObject("Object 3")

# 示例数组
array = [obj1, obj2]

# 检查数组中是否存在自定义对象
def check_object_in_array(obj, array):
    for i in range(len(array)):
        if obj.name == array[i].name:
            return i  # 返回索引值
    return -1  # 不存在时返回-1

# 调用函数进行检查
index = check_object_in_array(obj3, array)
if index != -1:
    print("数组中已存在该自定义对象，索引为", index)
else:
    print("数组中不存在该自定义对象")
