## Python Operator Precedence

If you use multiple operators in a single expression, the semantics of that expression depends on the assumed operator precedence. For example, consider the expression 2 + 4 * 0. Does Python calculate (2 + 4) * 0 or 2 + (4 * 0)? Depending on the operator precedence, the result would be 0 or …

## Python “is not” Operator — Checking Object Difference

The Python is not operator — consisting of two keywords is and not — tests if the left and right operands refer to a different object—in which case it returns True. It returns False if they refer to the same object. For example, the expression [1, 2, 3] is not [1, 2, 3] returns True …

## Python is Operator — Checking Identity

The Python is keyword tests if the left and right operands refer to the same object—in which case it returns True. It returns False if they are not the same object, even if the two objects are equal. For example, the expression [1, 2, 3] is [1, 2, 3] returns False because although both lists …

## Python Bitwise Operators [Full Guide + Videos]

Bitwise operators perform operations on the binary (bit) representation of integers. Background: Each integer is first written as a binary number that is a sequence of digits 0 or 1. For example: 0 is written as “0” 1 is written as “1” 2 is written as “10” 3 is written as “11” 4 is written …

## Python Logical Operators [Blog + Video]

Logical operators work on Boolean values but can be used on integers and other objects as well. Python has three logical operators: and, or, and not. The following table provides a quick overview of Python logical operators: Operator Description Example and Returns True if both operands are True, and False otherwise. (True and True) == …

## Python Arithmetic Operators

Arithmetic operators are syntactical shortcuts to perform basic mathematical operations on numbers. Operator Name Description Example + Addition Calculating the sum of the two operands 3 + 4 == 7 – Subtraction Subtracting the second operand from the first operand 4 – 3 == 1 * Multiplication Multiplying the first with the second operand 3 …

## Python Comparison Operators [Blog + Videos]

Comparison operators are applied to comparable objects and they return a Boolean value (True or False). Operator Name Description Example > Greater Than Returns True if the left operand is greater than the right operand 3 > 2 == True < Less Than Returns True if the left operand is smaller than the right operand …

## Python In-Place Assignment Operators

In-place assignment operators (also called compound assignment operators) perform an operation in-place on a variable provided as first operand. They overwrite the value of the first operand variable with the result of the operation when performing the operator without assignment. For example, x += 3 is the same as x = x + 3 of …

## Python In-Place Bitwise Left-Shift Operator

Python’s in-place bitwise left-shift operator x <<= y calculates the left-shift operation x << y, and assigns the result to the first operands variable name x. You can set up the in-place left-shift behavior in your own class by overriding the magic “dunder” method __ilshift__(self, other) in your class definition. The expression x <<= y …

## Python In-Place Bitwise XOR Operator

Python’s in-place bitwise XOR operator x ^= y calcualtes bitwise XOR x ^ y and assigns the result to the first operand x. To set this up for your own class, override the magic “dunder” method __ixor__(self, other) in your class definition. The expression x ^= y is syntactical sugar for the longer-form x = …
