The mod function also works with negative numbers. In this case, the result of the mod function will have the same sign as the divisor (the second argument). For example, the mod function for -10 % 3 would return 2, since -10 divided by 3 equals -3 with a remainder of -1, and ...

Python has the built-in function divmod(), which internally uses the modulo operator. divmod() takes two parameters and returns a tuple containing the results of floor division and modulo using the supplied parameters.Below is an example of using divmod() with 37 and 5:...
