什么是Pythonic方法来实现以下目标？
# Original lists:
list_a = [1, 2, 3, 4]
list_b = [5, 6, 7, 8]
# List of tuples from 'list_a' and 'list_b':
list_c = [(1,5), (2,6), (3,7), (4,8)]
每个成员list_c都是一个元组,其第一个成员来自list_a,而第二个来自list_b.
让我们来:
l = [[1, 2, 3], [4, 5, 6], [7, 8, 9]]
我正在寻找的结果是
r = [[1, 4, 7], [2, 5, 8], [3, 6, 9]]
并不是
r = [(1, 4, 7), (2, 5, 8), (3, 6, 9)]
非常感激
