Copied! Have a moment to study the output. It states some critical concepts in Python, which will help you compose greater plus more Pythonic code.
Because it seems, just how that personal computers identify the results of a modulo Procedure which has a negative operand leaves ambiguity as as to if the rest really get more info should go ahead and take indicator on the dividend (the number being divided) or maybe the indication with the divisor (the range by which the dividend is split).
