Operators in Python are used to perform operations on variables and values.In the example below, we use the + operator to add together two values:
=============================
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: Addition, Subtraction, Multiplication, Division, Modulus, Exponentiation, Floor division.
==========================================
Python Assignment Operators:
Assignment operators are used to assign values to variables:
==============================================
Python Comparison Operators:
Comparison operators are used to compare two values:
Equal, Not equal, Greater than, Less than, Greater than or equal to, Less than or equal to.
===========================================
Python Logical Operators:
Logical operators are used to combine conditional statements:
Returns True if both statements are true
Returns True if one of the statements is true
Reverse the result, returns False if the result is true
========================================
Python Identity Operators:
Identity operators are used to compare the objects, not if they are equal, but if they are actually the same object, with the same memory location:
Returns True if both variables are the same object, Returns True if both variables are not the same object.
=======================================
Python Membership Operators:
Membership operators are used to test if a sequence is presented in an object:
Returns True if a sequence with the specified value is present in the object,
Returns True if a sequence with the specified value is not present in the object
======================================
Python Bitwise Operators
Bitwise operators are used to compare (binary) numbers:
Name Description
AND Sets each bit to 1 if both bits are 1
OR Sets each bit to 1 if one of two bits is 1
XOR Sets each bit to 1 if only one of two bits is 1
NOT Inverts all the bits
Zero fill left shift Shift left by pushing zeros in from the right and let the leftmost bits fall off
Signed right shift Shift right by pushing copies of the leftmost bit in from the left, and let the rightmost bits fall off
====================================================
