Python implements two list corresponding element subtraction examples

This article is an example of how Python implements the subtraction of two corresponding list elements. To share for your reference, specific as follows:

Two corresponding element operations of list, take subtraction as an example:

# coding=gbk
v1 = [21, 34, 45]
v2 = [55, 25, 77]
#v = v2 - v1      # Error: TypeError: unsupported operand type(s) for -: 'list' and 'list'
v = list(map(lambda x: x[0]-x[1], zip(v2, v1)))
print("%s\n%s\n%s" %(v1, v2, v))

Operation results:

E:\Program\Python>del.py
[21, 34, 45]
[55, 25, 77]
[34, -9, 32]
