## Introduction to Operators

In this  article, we will  know  about  the  operators  in  python  and  the  types  of operators in python. In mathematics, to write an expression or equation, we use operators. For example, a+b in this expression ‘+’ operator is used. Similarly, in python, there are various types of operators, and they are used to write the expression or any condition. But the equations in mathematics and equations in python are a little bit different. In general, we write equation a+b=5 in this way. But in python, expression is always written to the right side of the ‘=’ operator. For example, 5=a+b. Now, let’s have a brief look at the types of operators.

## Types of Operators

Python operators are divided into the following categories
• Arithmetic Operators
• Assignment Operators
• Comparison / Relational Operators
• Logical Operators
• Identity Operators
• Membership Operators
• Bitwise Operators

### Arithmetic Operators in Python

Python  supports  all  arithmetic  operators  like +, -, /, *,  etc. Following  are  the arithmetic operators in python.
Look at the following code to know the working of each arithmetic operator in python
``````x=10
y=5
# Subtraction
print('Subtraction:',x-y)
# Multiplication
print('Multiplication:',x*y)
# Division
print('Division:',x/y)
# Division in python, Quotient after integer (whole number) division
print("Floor division",x//y)
# Remainder after integer (whole number) division; also called modulo operator python
print('Modulo:',x%y)
# Exponentiation or power (x power of y)
print("Exponential:",x**y)``````
Output
``````Addition: 15
Subtraction: 5
Multiplication: 50
Division: 2.0
Floor division 2
Modulo: 0
Exponential: 100000``````

### Assignment Operators in python

Python has a special set of  operators  known  as  compound  assignment  operators,  which can help you write code efficiently because they work as a shortcut. Compound operators are a combination of two operators. Following are the assignment operators in python.
See the following code to have a brief idea about assignment operators
``````x=20
y=4
x += y # Addition also equivalent to x = x + y
print(x)
x -= y # Subtraction also equivalent to x = x - y
print(x)
x *= y # Multiplication also equivalent to x = x * y
print(x)
x /= y # Division also equivalent to x = x / y
print(x)
x //= y # Floor Division also equivalent to x = x // y
print(x)
x %= y # Modulus also equivalent to x = x % y
print(x)
x **= y # Exponentiation also equivalent to x = x ** y
print(x)``````
Output
``````24
20
80
20.0
5.0
1.0
1.0``````

### Comparison / Relational Operators in python

Relational  operators  are also  known as  comparison  operators in  python.  Comparison operators are mostly used in Boolean expressions. And the value of the expression is always true or false.  Syntax to use relational operators is as follow:
Operand1  Comparison Operator operand2
Following are the comparison operators in python.
See the following code to have a brief idea about relational operators:
``````x=20
y=4
print('Greater than',x>y)
print('Less than',x<y)
print('Greater than equals to',x>=y)
print('Less than equals to',x<=y)
print('Equals to ',x==y)
print('Not equals to',x!=y)
``````
Output
``````Greater than True
Less than False
Greater than equals to True
Less than equals to False
Equals to False
Not equals to True``````

### Logical Operators / boolean operators python

The  relationship  between  two  Boolean  expressions is  denoted by  logical  operators in python. Logical operators are also known as boolean operators python. Two or more conditions can be combined using logical operators. The syntax for using logical operator is:
Condition1   logical_operator  Condition2
Following are the logical operators used in python
See the following code to have a brief idea about logical operators
``````a=10
b=a+2
print((a>5) and (b>a)) #and operator
print((a>15) or (b>a)) #or operator
print(a!=b)   #not operator``````
Output
``````True
True
True
``````

### Identity Operators

Identity  operators in  python are  used to  check  if both the  operators have the same memory location or not.  Following are the identity operators used in python:
{1, 2, 3, 4, 5, 6}
set()
>
Coding example:
``x=10y=xprint(x is y)print(x is not y)``
Output
``````True

False``````

### Membership Operators

Membership  operators in  python are  used to check  if the given  value is  present in the object or not.  Following are the membership operators used in python:
Coding example:
``x=[1,2,3,4,5]print(1 in x)print(2 not in x)``
Output
``````True

False
``````

### Bitwise Operators

Bitwise operators  in python are  used to  compare  numbers.  &  operator in  python is the most popular operator.  Following are the bitwise operators used in python:

## Summary

In this article, we have learned about operators and types of operators in python. Operators are used to performing operations and used in the expressions. There are the following types of operators in python: arithmetic operators, assignment operators, relational or conditional operators, logical operators, membership operators, and bitwise operators.
