Operators in Python is very use full to perform any operation and logic.
Operators are special symbols that carry out arithmetic or logical or any other computation.
Python can construct which symbol can we used to manipulate the value of the operands.
In python basically six type of operators available, that listed are as under
 Arithmetic Operators
 Relational Operators
 Logical Operators
 Bitwise Operators
 Assignment Operators
 Special Operators
1) Arithmetic Operators
Arithmetic operators are used to perform mathematical operations like addition, subtraction, multiplication etc..
2) Relational Operators
These are also known as Comparison operators.
Relational operators are used to compare or relate the values.
It either return True or False according to the condition.
3) Logical Operators
The logical operators for And, Or and Not are used to combine simple relational statements into more complex expressions.
4) Bitwise Operators
Bitwise operators act on the operands as if they were strings of binary digits.
It operates bit by bit, hence the name bitwise operator.
The bitwise operator works at bit and performs bit by bit operations in Python.
Operator  Meaning 

&  Bitwise AND 
  Bitwise OR 
~  Bitwise NOT 
^  Bitwise XOR 
>>  Bitwise right shift 
<<  Bitwise left shift 
5) Assignment Operators
Assignment operators are used in python to assign values to variables.
Here,
a = 5 is a simple assignment operator that assigns the value on the right, to the variable a on the left.
Operator  Example  Equivalent to 

=  x = 5  x = 5 
=  x = 5  x = x – 5 
*=  x *= 5  x = x * 5 
/=  x /= 5  x = x / 5 
%=  x %= 5  x = x % 5 
//=  x //= 5  x = x // 5 
**=  x **= 5  x = x ** 5 
&=  x &= 5  x = x & 5 
=  x = 5  x = x  5 
^=  x ^= 5  x = x ^ 5 
6) Special Operators
Python language provides some special types of operators,
 Identity Operators
 Membership Operators


Identity Operators

“is” and “is not” are the identity operators in python.
This is used to check if two variables are located on the same part of the memory.
Two variables that are equal, do not imply that they are identical.
Operator  Meaning  Example 

is  If True, refer to the same object.  a is b 
isnot  If True, do not refer to the same object.  a is not b x 
Make one file called as special_operators.py
#Identity Operators a1 = 5 b1 = 5 a2 = 'Hello' b2 = 'Hello' a3 = [1,2,3] b3 = [1,2,3] print(a1 is not b1) print(a2 is b2) print(a3 is b3)


Membership Operators

“in” and “not in” are the membership operators in python.
This is used to test whether a variable is found in a sequence or not.
Note : In a dictionary, a user can only test for the key, not the value.
Operator  Meaning  Example 

in  True if value is found in the sequence  5 in x 
notin  True if value is not found in the sequence  5 not in x 
create python file name as special_operators.py
#Membership Operators x = "Hello world" y = {1:'a',2:'b'} print('H' in x) print('hello' not in x) print('Hello' not in x) print(1 in y) print('a' in y)
