    Since you tagged python, isinstance(var, bool) ?

    PS. I hate and try not to use python, but if I recall correctly there's some oddities with bools and ints so not sure if it'd work

    @ScriptCoded bool returns 0 or 1 if used arithmetically

    I don't know about python but !!x is always a classic one

    Edit: `not not x` seems to do the trick

    @123abc Hm okay, no logical operators

    How about just `1-bool`. It doesn't evaluate to a boolean but I don't think your original expression does either

    Branchless always fascinated me. I don't do it in python because I like to use python as more of a clean to read but less efficient tool. But in C++ I love these

    While this might be a good brain exercise, aren't a lot of compilers doing the optimisation step for you anyway?

    @kamen i guess it's more about code aesthetics, ya know, having less lines of code... wait no, that's horrible code aesthetics. A lame excuse to have a seemingly better Maintainability Index for saving 2 lines of code

    Would then '1 - boolean' work?
