Python Operators

Introduction

 
In this article, I'll take you through the type of operators we do use in Python. These are:
 

Operators in Python

 
  • Arithmetic Operators
  • Special Operators
  • Comparison Operators
  • Bitwise Operators
  • Assignment Operators
  • Identity Operators

Arithmetic Operators

 
For performing the base mathematical operations or some other type of math-related functionality we use Arithmetic Operators.
 
Let's take a close look at all these operators.
 
Operator Description Example
Addition Adds both operands together z=x+y
Subtraction Subtracts the right-side operand from the left-side operand z = x – y
Multiplication Multiplies both operands together z = x * y
Division Divides the left-side operand with the right-side operand z = x / y
Modulus It takes a modulus using two operands and assigns the result to the left z = x % y

Special Operators

 
 Actually these are not special operators, these are a subset of mathematical operators, that does the same functionality as general mathematical operators do.
 
Let's take a close look at all these operators.
 
Operator Description Example
Exponent Does exponential operations x ** y = x ^ y
Floor Division Takes the result of the quotient and rejects the mantissa 5 // 2 = 2

Comparison Operators

 
The comparison operators are used to compare the values of both sides of the operators and do specific operations based on them.
 
Let's take a close look at all these operators.
 
Operator Description Example
== Compares both the left and right operands and depending on the result, displays either True or False (2 == 3) false
> Compares the left operand with the right operand and depending on the result, (greater) displays either True or False (3 > 2) true
< Compares the left operand with the right operand and depending on the result, (left) displays either True or False (3 < 2) true
!= If the values of the two operands aren't equal, then displays the condition accordingly (3 != 2) true
<> If the values of both operands aren't equal then the condition becomes true (3 <> 2) true
>= If the value of the left operand is greater than the right-side operand, then the condition becomes true (3 >= 2) true
<= If the value of the left operand is greater than the right-side operand, then the condition becomes true (3 <= 2) false

Bitwise Operators

 
Bitwise operators are bit-oriented operators. Here bit-oriented means that these operators work on the bits and do the action bit by bit.
 
Let's take a close look at all these operators.
 
Operator Description Example
& (Binary AND) It copies a bit to the result if it exists in both operands (x & y)
| (Binary OR) It copies a bit if it exists in either operand (x | y)
~ (Binary One's Complement) It's used for flipping bits (~x)
^ (Binary XOR) It copies the bit if it is set in one operand but not both (x ^ y)
<< (Binary Left Shift) It shifts the value to the left specified by the right operand x << 2
>> (Binary Right Shift) It shifts the value to the right specified by the right operand x >> 3

Assignment Operators

 
As the name suggests, assignment operators are used for assigning values, for example to a variable when performing certain operations.
 
Let's take a close look at all these operators.
 
Operator Description Example
= It assigns a value from the right-side operand to the left side z = x + y (value of x + y -> z )
+= Adds and it adds the right operand to the left operand and assigns the result to the left operand z += x (z = z + x)
-= Subtracts and it subtracts the right operand from the left operand and assigns the result to left operand z -= x (z = z - x)
*= Multiplies and it multiplies the right operand with the left operand and assigns the result to the left operand z *= x (z = z * x)
/= Divides and it divides the left operand by the right operand and assigns the result to the left operand z /= x (z = z / x)
%= Takes the modulus using the two operands and assigns the result to the left operand z %= x (z = z % x)

Identity Operators

 
Identity operators are used to comparing the memory locations of two objects (compare the locations).
 
Let's take a close look at all these operators.
 
operator Description Example
is Evaluates whether the values on either side are equal or not and acts (if true) accordingly. If x is y results True
Is NOT Evaluates whether the values on either side are equal or not and acts (if false) accordingly. If x is not y result False
