列表理解同时迭代两个变量 [英] List comprehension iterate two variables at the same time

问题描述

是否有可能使用列表理解同时迭代两个变量，同时增加两个变量的循环位置.请参见下面的示例:

Is it possible that with the use of list comprehension to iterate through two variables at the same time increasing the loop position in both at the same time. See example below:

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

b = [6,7,8,9,10]

c = [i+j for i in a for j in b] # This works but the output is not what it would be expected.

预期输出为 c = [7, 9, 11, 13, 15](来自 a 的第 n 个元素 + 来自 b 的第 n 个元素)

expected output is c = [7, 9, 11, 13, 15] (n'th element from a + n'th element from b)

谢谢.

推荐答案

a = [1,2,3,4,5]
b = [6,7,8,9,10]

c = map(sum, zip(a, b))
print c

#Output
[7, 9, 11, 13, 15]
