您的方法非常接近,但您需要先展平:from itertools import chainmy_list = [[(12, 1), (10, 3), (4, 0), (2, 0)], [(110, 1), (34, 2), (12, 1), (55, 3)]]my_list2 , my_list3 = map(list,zip(*chain.from_iterable(my_list)))my_list2# [12, 10, 4, 2, 110, 34, 12, 55]my_list3# [1, 3, 0, 0, 1, 2, 1, 3]

一种不同的,简单的方法:my_list = [[(12, 1), (10, 3), (4, 0), (2, 0)], [(110, 1), (34, 2), (12, 1), (55, 3)]]first = []second = []for inner in my_list: for each in inner: first.append(each[0]) second.append(each[1])print(first) # [12, 10, 4, 2, 110, 34, 12, 55]print(second) # [1, 3, 0, 0, 1, 2, 1, 3]

您可以使用列表理解 (5.1.3)。元组的第一个数字:my_list2 = [tuple[0] for inner in my_list for tuple in inner]第二个元组数:my_list3 = [tuple[1] for inner in my_list for tuple in inner]

这个怎么样?my_list = [[(12, 1), (10, 3), (4, 0), (2, 0)], [(110, 1), (34, 2), (12, 1), (55, 3)]]flatten = lambda l: [item for my_list in l for item in my_list]list1, list2 = zip(*flatten(my_list))
