Apr 25, 2017 · The percentage sign is an operator in Python. It's described as: x % y remainder of x / y So it gives you the remainder/rest that remains if you "floor divide" x by y. Generally (at least in Python) given a number x and a divisor y: x == y * (x // y) + (x % y) For example if you divide 5 by 2: >>> 5 // 2 2 >>> 5 % 2 1 >>> 2 * (5 // 2) + (5 % 2) 5
Python divides the operators in the following groups: Arithmetic operators. Assignment operators. Comparison operators. Logical operators. Identity operators. Membership operators. Bitwise operators. Python Arithmetic Operators. Arithmetic operators are used with numeric values to perform common mathematical operations: Python Assignment Operators.
Python’s in and not in operators allow you to quickly determine if a given value is or isn’t part of a collection of values. This type of check is common in programming, and it’s generally known as a membership test in Python. Therefore, these operators are known as membership operators. In this tutorial, you’ll learn how to:
