Is there a way to generate permutations of large arrays of sizes say,in the

This is not true for float("nan"), though. The question is, is your
above statement a valid optimization for the 'in' operator, or not?
And no, it isn't, because it's not perfectly safe. How

It may be obvious, but it's not necessarily true. Some commonly-used
values – for example, an “null” – are not equal to themselves, by
definition.
It is fine to define such a type in Python, because ‘

It's been brought up on Stack Overflow that the "in" operator (on

You should have known better than to make gendered slurs. Claiming “it
