Swapping 1 with 0 and 0 with 1 in a Pythonic way

Question

In some part of my Python program I have a val variable that can be 1 or 0. If it\'s 1 I must change to 0, if it\'s 0 I must change to 1.

How do you do it in a Pytho

Answer 1

Just another possibility:

i = (1,0)[i]

This works well as long as i is positive, as dbr pointed out in the comments it doesn't work fail for i < 0.

Are you sure you don't want to use False and True? It sounds almost like it.
