将一维列表转换为多维列表

Question

例如，我有两个列表

a = [1,2,3]
b = [4,5,6]

我想制作一个格式为

的列表c

c = [[1,4],[2,5],[3,6]]

由于我是Python的新手，任何人都可以帮助我。 谢谢。

Answer 1

使用zip（示例代码为Python 2样式）：

a = [1, 2, 3]
b = [4, 5, 6]
print zip(a, b)
# [(1, 4), (2, 5), (3, 6)]

Python 3风格：

a = [1, 2, 3]
b = [4, 5, 6]
print(list(zip(a, b)))
# [(1, 4), (2, 5), (3, 6)]

Answer 2

如果你真的想要内部列表而不是元组，你可以使用：

a = [1,2,3]
b = [4,5,6]
c = [list(result) for result in zip(a,b)]
# c = [[1,4],[2,5],[3,6]] 

Answer 3

a = [1,2,3]
b = [4,5,6]
c = zip(a,b)
c = [list(k) for k in c]
