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:

[21, 34, 45]
[55, 25, 77]
[34, -9, 32]
