Python's "in" and "not in" Operators: Check for Membership

Python’s in and not in operators allow you to quickly check if a given value is or isn’t part of a collection of values. This type of check is generally known as a membership test in Python. Therefore, these operators are known as membership operators. By the end of this tutorial, you’ll understand that:

operator — Standard operators as functions — Python 3.13.3 documentation

The operator module provides efficient functions that correspond to the intrinsic operators of Python, such as operator.add(x, y) for x+y. Learn how to use these functions for object comparisons, logical operations, mathematical operations, sequence operations, and more.

Operator Functions in Python | Set 1 - GeeksforGeeks

Python has predefined functions for many mathematical, logical, relational, bitwise etc operations under the module "operator". Some of the basic functions are covered in this article. 1. add (a, b) :- This function returns addition of the given arguments. Operation - a + b. 2. sub (a, b) :- This function returns difference of the given arguments.

The in Operator in Python (for List, String, Dictionary)

x in y returns True if x is included in y, and False otherwise. The in operator can be used not only with list, but also with other iterable objects such as tuple, set, and range. Details about dictionaries (dict) and strings (str) are described later. The in operator tests for value equality.

Python “in” and “not in” Membership Operators: Examples and Usage

Python has many built-in operators to perform various operations, among them membership operators “in” and “not in” are used to check if something specific is present in iterable or not. Python uses these operators frequently to make search operations easier and more efficient.

Using ‘in’ with Python | Membership Operators Guide

TL;DR: How Do I Use the ‘in’ Operator in Python? The 'in' operator in Python is used to check if a value exists in a sequence like a list, tuple, or string. EX: print(1 in list) prints True if the value 1 is found in list, and False otherwise. Here’s a simple example:

Python Membership and Identity Operators - GeeksforGeeks

Python offers two membership operators to check or validate the membership of a value. They are as follows: The in operator is used to check if a character/substring/element exists in a sequence or not. Evaluate to True if it finds the specified element in a sequence otherwise False.

The operator Module in Python: itemgetter, attrgetter, methodcaller

In Python, the operator module provides functions for the built-in operators and functions to create callable objects that fetch items, attributes, and call methods. operator.itemgetter(), operator.attrgetter(), and operator.methodcaller() are often used for the key argument in functions like sorted(). See the following article for details.

Python Operators - GeeksforGeeks

In this article, we will look into different types of Python operators. OPERATORS: These are the special symbols. Eg- + , * , /, etc. OPERAND: It is the value on which the operator is applied. Python Arithmetic operators are used to perform basic mathematical operations like addition, subtraction, multiplication and division.
