The Basic Operators In Python

Introduction

 

In this article, I will explain the basic operators in Python.

 

Definition

 

An operator is a symbol which represents some operations that can be performed on data. There are different types of operators in Python. There are:

1. Arithmetic operators
2. Relational operators
3. Logical operators
4. Assignment operators

Arithmetic operators

 

Arithmetic operators are used to perform arithmetic operations.

 

Syntax

Variable 1 arithmetic operator variable 2

The arithmetic operators and their meaning are given in the below table:

 

operators	operations
+	Addition
-	Subtraction
*	Multiplication
/	Division
%	Modulo division

 

Example

x = 10
y = 2

print(x + y)#Addition
print(x - y)#Subtraction
print(x * y)#Multiplication
print(x / y)#Division
print(x % y)#Modulo division

Output

 

 

Relational operators

 

Relational operators are used to compare two or more operans. It evaluates whether the given expression is true or false.

 

operators	operations
<	is less than
<=	is less than or equal
>	is greater t
>=	is greater than or equal
==	is equal to
!=	is not equal to

 

Syntax

Variable 1 relational operator variable 2

Example

x = 20
y = 10

print(x == y)# returns False because 20 is not equal to 10
print(x != y)#returns True because 20 is not equal to 10
print(x > y)#returns True because 20 is greater than 10
print(x < y)#returns False because 20 is not less than 10
print(x >= y)#returns True because 20 is greater, or equal, to 10
print(x <= y)#returns False because 20 is neither less than or equal to 10

Output

 

 

Logical operators

 

They are used to combine the result of two or more conditions.

 

operators	operations
&&	And
||	Or
!	Not

 

Syntax

Variable 1 logical operator variable 2

Example

x = 8

print(x > 3 and x < 10)# returns True because 8 is greater than 3 AND 8 is less than 10
print(x > 3 or x < 1)# returns True because one of the conditions are true
print(not(x > 3 and x < 11))#returns False because not is used to reverse the result

Output

 

 

Assignment operators

 

Assignment operators have to assign a value or an expression or a value of a variable to another variable. Assignment operators use arithmetic operators (+, -, *, /) along with assignment operator (=).

 

operators	Example	Meaning
+=	X+=Y	X=X+Y
-=	X-=Y	X=X-Y
*=	X*=Y	X=X*Y
/=	X/=Y	X=X/Y
%=	X%=Y	X=X%Y

 

Syntax

Variable 1 assignment operator variable 2

Example

a = 10
b = 10
c = 10
d = 10
e = 10

a += 20#Addition
b -= 20#Subtraction
c *= 20#Multiplication
d /= 20#Division
e %= 20#Modulo division

print(a)
print(b)
print(c)
print(d)
print(e)

Output
