Maybe you are looking for floor division? https://docs.python.org/3.3/reference/expressions.html#binary-arithmetic-operations > The / (division) and // (floor division) operators yield the quotient of their arguments. The numeric arguments are first converted to a common type. Division of integers yields a float, while floor division of integers results in an integer; the result is that of mathematical division with the ‘floor’ function applied to the result. Division by zero raises the ZeroDivisionError exception. Python 3.8 >>> 17 / 3 5.666666666666667 >>> 17.0 / 3 5.666666666666667 >>> 17 // 3 5 |

If you're using Python 2.7 then that would explain what you're seeing. You can either upgrade to Python 3 or use `from __future__ import division` to get the result you're after. |
