All these answers are saying True, and that's right, but many of them suggest if an integer is greater than zero it's True, and that's not quite right - in effect, a coercion of an integer to boolean is performing x != 0, so negative numbers also end up as True:

'True' because 12+5=17 (int) and bool(int>0) = True

Result will be 'True' because by default, all Python Boolean values greater than 0 result to True.

Via the decoupling a becames 12 and b becames 5 thus their joined sum becames 17. Since 17 is a truthy value it passed the if check and thus prints True
