To get the remainder, use %. Python “knows” that the values stored in x and y have type int because there are no decimal points in those assignments. >>> x = 30 >>> y = 8 >>> q = x/y >>> print q 3 >>> r = x%y >>> print r 6 . float Arithmetic Python “knows” that the values stored in x and y have type float because there are decimal points in those assignments. >>> x = 30. >>> y = 8 ...

One has decimal points, and one does not, but both are still interpreted in Python as numeric. The IDE shows these lines in different colors so that you can tell the number variables from the string variables. Expressions can be used to concatenate the strings and to perform math on the numbers. The graphic in step 2 shows an example of concatenating string variables with the plus sign ...

throw away the decimal part, which actually raises a negative value. Finally, math.ceil is the opposite of math.floor, raising non{integral values. Why is the oor division operator useful? If we want to make change for 84 cents, we can use oor division to determine how many quarters to give: 84//25, which returns a result of 3: the same as math.floor(3.36). Modulo: The % operator in Python can ...
