I love something = condition and result1 or result2 in lua

Python does that, too.

Are you just referring to how Python uses the English and/or instead of the more common &&/||? I think what the user above you was talking about was Lua's strange ternary syntax using and/or.

no, the linked table shows how python also returns the first non-falsey result of an a or b expression rather than just giving a boolean. it's useful for initialising optional reference args:

def foo(a: list = None)
    a = a or []

works with and as well.

often I do a function called elvis XD with the next signature elvis(condition, res1, res2)
