获取两个列表之间的区别？

Question

我必须列出数字，我想保存每个并行单元格之间的差异 我需要这样的东西：

diffEx = [(myEx - opEx) for myEx,opEx in (myExeptPack,opExeptPack)]

例如。

listA = [1,2,3]
listB = [4,3,2]
diff = [-3,-1,1]

谢谢

Answer 1

使用zip功能：

diffEx = [(myEx - opEx) for myEx,opEx in zip(myExeptPack,opExeptPack)]

Answer 2

您可以使用map使语句比使用zip时更简洁：

import operator
diffEx = map(operator.sub, myExeptPack, opExeptPack)
