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

    In your case I recommend the ternary:

    val = 0 if val else 1
    

    If you had 2 variables to swap you could say:

    (a, b) = (b, a)
