Operators in Python

September 12, 2023

Operators

Operators are used to performing some operation between some values of any data types. We have seven different types of Operators in Python and can perform any operation but are differentiated according to their usage. Like when we add two numbers we use addition operators between those numbers which can be int, or float, or can be of another data type.

Arithmetic Operators in Python

Arithmetic operators are used to performing mathematical operations like addition, subtraction, multiplication, division, etc. Arithmetic operators can be set in between operands. In mathematical operations elements on which operation is supposed to be done are called operand and the type of operation is performed by the operator used between two operands.

Operator	Name of Operator	Example
+	Addition	Prep + Insta
–	Subtraction	Prep – Insta
*	Multiplication	Prep * Insta
/	Division	Prep / Insta
%	Modulus	Prep % Insta
**	Exponentiation	Prep ** Insta
//	Floor Division	Prep // Insta

Run

a = 5
b = 9
print(a+b) #Addition
print(a-b) #Subtraction
print(a*b) #Multiplication
print(a/b) #Division
print(a%b) #Modulus
print(a**b) #Exponentiation
print(a//b) #Floor Division

Output:
14
-4
45

Assignment Operators in Python

The assignment operator is used to assigning values to the variable in many different ways, we can assign values by incrementing, decrementing, or by performing any other operation and then assigning the value to the variable. We have 13 assignment operators to assign values to the variable.

Operator	Also be used as	Example
=	a = 5	a = 5
+=	a = a+5	a+=5
-=	a = a-5	a-=5
*=	a = a * 5	a*=5
/=	a = a/5	a/=5
%=	a = a%5	a%=5
//=	a = a//5	a//=5
**=	a = a **5	a**=5
&=	a = a&5	a&=5
\|=	a = a\|5	a\|=5
^=	a = a^5	a^=5
>>=	a = a>>5	a>>=5
<<=	a = a<<5	a<<=5

Run

a = 5
b = a #Assign Operator
print(b)

b += a #Add and assign operator
print(b)

b -= a #Subtract and assign operator
print(b)

b %= a #Modulus and assign operator
print(b)

b >>= a # Bitwise right shift operator
print(b)

Output:
5 
10
5

Comparison Operators in Python

A comparison operator is used to comparing two or more variables or constants having some values. We can compare different variables or constants in six different ways that include, comparing if two values are equal, or if two values are not equal, and many other ways.

Operator	Name of Operator	Example
==	Equal	a == b
!=	Not equal	a != b
>	Greater than	a > b
<	Less than	a < b
>=	Greater than or equal to	a >= b
<=	Less than or equal to	a <= b

Run

a = 5
b = 10
print(b == a) #Equal operator
print(b != a) #Not equal operator
print(b > a)  #Greater than operator
print(b < a) #Less than operator print(b >= a) #Greater than or equal to operator
print(b <= a) #Less than or equal to operator

Output:
False
True
True
False
True
False

Logical Operators in Python

The logical operator is used to perform some logical operations or combine conditional statements. Mainly logical operators are used in control statements like if, else, and elif where we can check more conditions together just by using these operators. Logical operators always return TRUE or FALSE values.

Operator	About	Example
and	TRUE if both are true	a > 5 and a > 10
or	TRUE if any one is true	a > 5 or a > 10
not	Converts TRUE to FALSE	not(TRUE)

Run

a = True
b = False
print(a and b) #AND operator
print(a or b) #OR operator 
print(not a) #NOT operator

Output:
False
True
False

Identity Operators in Python

Identity operators are used in Python programing language to check if the two values, variables, or constants are not only the same but also have the same memory location. These types of operators are used to compare and check the exact match of the values between two objects.

Operator	About	Example
is	Returns TRUE if a and b both are same	a is b
is not	Return TRUE if a and b both are not same	a is not b

Run

a = 5
b = 9
print(a is b) #is operator
print(a is not b) #is not operator

Output:
False
True

Membership Operators in Python

Membership operatorsin python are used for checking if the iterator or the given value is present in the sequence or not. These types of operators always return values in a TRUE or FALSE format. If the value is found in the sequence then the operator will return TRUE else the operator will return FALSE.

Operator	About	Example
in	Returns TRUE if the iterator is present in sequence	a in b
not in	Returns TRUE if the iterator is not present in sequence	a not in b

Run

a = 5
b = 9
list = [5,10,15,20]
print(a in list) #in operator
print(a not in list) #not in operator

Output:
True
False

Bitwise Operators in Python

These operators are used to compare the binary numbers. We can perform different operations on binary numbers such as and, or, xor, not, left shift, and right shift. Sometimes these operators are also called bitwise-or, bitwise-and, and bitwise-xor and so on. Shift operators are used to shifting the values of the binary number to left or right.

Operator	Name	About
&	AND	Return 1 if both are TRUE or 1
\|	OR	Return 1 if one of them are TRUE or 1
^	XOR	Return 1 if only one is TRUE or 1
~	NOT	Inverse
<<	Left shift	Shifting bits to the left
>>	Right shift	Shifting bits to the right

Run

a = 5
b = 9
print(a & b) #Bitwise AND operator
print(a | b) #Bitwise OR operator 
print(a ^ b) #Bitwise XOR operator 
print(~a) #Bitwise NOT operator 
print(a << b) #Bitwise Left Shift operator 
print(a >> b) #Bitwise Right Shift operator

Output:
