  if (condition && condition1 && condition2)

    The problem with this in the OP is the first ‘if’ checks if the object exists and the second gets a property of said object only if the original object exists.

    I’m not saying the OP is good code, but chaining them like this would result in exceptions.

      Not in a language with short circuiting.

        Could’ve sworn I’ve had this issue before! Maybe not with python

      The language is python and it has short circuiting aka in an and condition, if the first block isn’t fulfilled the second one isn’t tested because it’s unnecessary.

      Same with or and the reverse.

    “Yeah x might be less than 10 but just in case check if it’s less than 30.”

    This is the cursed case when you case the forbidden scroll of the ancients: switch (true) { }

  I’m so the latter. The former drives me fucking crazy.

  Add the else branches to the nested version and log the failed conditions (to make it more obvious).

  if(!condition) {  return;}: If(!condition1) {return;}; if(!condition2) {return;};
