I love something = condition and result1 or result2 in lua
- Python does that, too.
  https://docs.python.org/3/library/stdtypes.html#boolean-operations-and-or-not
  
  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:
  undefined
  
  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)
