如何将列表合并到元组列表中? [英] How to merge lists into a list of tuples?

问题描述

实现以下目标的 Pythonic 方法是什么?

What is the Pythonic approach to achieve the following?

# 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)]

list_c 的每个成员都是一个元组，其第一个成员来自 list_a，第二个成员来自 list_b.

Each member of list_c is a tuple, whose first member is from list_a and the second is from list_b.

推荐答案

在 Python 2 中:

In Python 2:

>>> list_a = [1, 2, 3, 4]
>>> list_b = [5, 6, 7, 8]
>>> zip(list_a, list_b)
[(1, 5), (2, 6), (3, 7), (4, 8)]

在 Python 3 中:

In Python 3:

>>> list_a = [1, 2, 3, 4]
>>> list_b = [5, 6, 7, 8]
>>> list(zip(list_a, list_b))
[(1, 5), (2, 6), (3, 7), (4, 8)]
