如何从非连续数字列表创建范围显示？

def create_range_display(numbers):
    numbers.sort()  # 将数字列表按升序排列
    ranges = []
    start = numbers[0]
    end = numbers[0]

    for i in range(1, len(numbers)):
        if numbers[i] == end + 1:
            end = numbers[i]
        else:
            ranges.append((start, end))
            start = numbers[i]
            end = numbers[i]

    ranges.append((start, end))  # 处理最后一个范围

    # 将范围转换为字符串显示
    range_display = ""
    for range in ranges:
        if range[0] == range[1]:
            range_display += str(range[0]) + ", "
        else:
            range_display += str(range[0]) + "-" + str(range[1]) + ", "

    range_display = range_display[:-2]  # 去除最后的逗号和空格

    return range_display

# 示例输入
numbers = [1, 2, 3, 6, 7, 8, 10, 11, 12, 15]
range_display = create_range_display(numbers)
print(range_display)
