如何对"NameOfClass“类型的数组进行排序

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

# 自定义比较函数，按照对象的age属性进行排序
def compare(obj1, obj2):
    if obj1.age < obj2.age:
        return -1
    elif obj1.age > obj2.age:
        return 1
    else:
        return 0

# 排序函数，使用快速排序算法
def quick_sort(arr):
    if len(arr) <= 1:
        return arr
    pivot = arr[len(arr) // 2]
    less = [x for x in arr if compare(x, pivot) < 0]
    equal = [x for x in arr if compare(x, pivot) == 0]
    greater = [x for x in arr if compare(x, pivot) > 0]
    return quick_sort(less) + equal + quick_sort(greater)

# 示例数据
array = [NameOfClass("John", 25), NameOfClass("Alice", 30), NameOfClass("Bob", 20)]

# 对数组进行排序
sorted_array = quick_sort(array)

# 输出排序结果
for obj in sorted_array:
    print(obj.name, obj.age)
