What is the proper to do the difference between two tuple in python [duplicate]

Question

I'm looking for the proper way to do the difference between 2 tuples. For example:

a = (1, 2, 3)
b = (1, 0, 2)

Difference expected

(0, 2, 1)

I know I can iterate on both tuples create a new tuple then do the difference but i'm looking for something more conventional or proper.

Answer 1

You may access both indices in same iteration with help of zip built-in. After that you simply feed generator expression to tuple to create new tuple object.

diff = tuple(x-y for x,y in zip(a,b))

Answer 2

from operator import sub
a = (1, 2, 3)
b = (1, 0, 2)
tuple(map(sub, a, b))

(0, 2, 1)
