如何将列表合并到元组列表中?
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.
解决方案
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)]
