>>> colors = ["BLACK", "WHITE"]
>>> sizes = ["WS", "WM", "WL", "S", "M", "L", "XL", "2XL", "3XL", "4XL"]
>>>
>>> # 请使用列表推导式，统计得出下面的结果
>>>
>>> result
[['BLACK', 'WS'], ['BLACK', 'WM'], ['BLACK', 'WL'], ['BLACK', 'S'], ['BLACK', 'M'], ['BLACK', 'L'], ['BLACK', 'XL'], ['BLACK', '2XL'], ['BLACK', '3XL'], ['BLACK', '4XL'], ['WHITE', 'WS'], ['WHITE', 'WM'], ['WHITE', 'WL'], ['WHITE', 'S'], ['WHITE', 'M'], ['WHITE', 'L'], ['WHITE', 'XL'], ['WHITE', '2XL'], ['WHITE', '3XL'], ['WHITE', '4XL']] 本帖最后由 hveagle 于 2022-7-5 13:56 编辑
