如何将商品数据转换为 [标题, 颜色, 尺码, 数量, 标题总数量] 格式？

from collections import counter# 计算每个 (标题, 颜色, 尺码) 的数量counter = counter(tuple(x[:-1]) for x in data)# 计算每个标题的总数title_counts = counter(x[0] for x in data)# 构建结果列表result = [(key[0], key[1], key[2], count, title_counts[key[0]]) for key, count in counter.items()]# 根据总数从高到低排序result.sort(key=lambda x: (-x[4], x[0], x[1], x[2]))print(result)

[    ('连衣裙', '白色', 'S', 2, 3),    ('连衣裙', '黑色', 'M', 1, 3),    ('裤子', '白色', 'S', 1, 1),]
