Using tuples instead of boolean operators

Question

Is there a difference (in terms of performance, not readability) between the following ways of evaluating two (or more) conditions linked by and?

a == 1 and b == 2

or

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

The same for or:

a == 1 or b == 1

or

1 in (a,b)

Which way is preferable? The one using boolean operators or the other one using tuples?

Answer 1

Using and/or operators are almost always better in terms of performance (perhaps not for readability but that's another issue): 1. They avoid having to create tuple objects like you do in other examples which will be more costly in terms of space/time complexity 2. They short-circuit meaning there is a good chance you can avoid executing unnecessary portions of the code.
