What is Operators and Operands?
Operators are special symbols that represent computations like addition and multiplication. The values the operator is applied to are called operands. Python language supports the following types of operators:
Python Arithmetic Operators :
Assume variable a = 10 and variable b = 20, then :
Operators 
Description 
Example 
+ Addition 
Adds values on either side of the operator 
a + b = 30 
 Subtraction 
Subtracts right hand operand from left hand operand 
a – b = 10 
* Multiplication 
Multiplies values on either side of the operator 
a * b = 200 
/ Division 
Divides left hand operand by right hand operand 
b / a = 2 
% Modulus 
Divides left hand operand by right hand operand and returns remainder 
b % a = 0 
** Exponent 
Performs exponential (power) calculation on operators 
a**b =10 to the power 20 
// 
Floor Division 
9//2 = 4 and 9.0//2.0 = 4.0, 11//3 = 4, 11.0//3 = 4.0 
Note : The division of operands where the result is the quotient in which the digits after the decimal point are removed. But if one of the operands is negative, the result is floored, i.e., rounded away from zero (towards negative infinity)
Example :
 a = 10
 b = 20
 c = 0
 c = a + b
 print ("\n Addition  Value of c is ", c)
 c = a  b
 print ("\n subtraction  Value of c is ", c)
 c = a * b
 print ("\n Multiplication  Value of c is ", c)
 c = b / a
 print ("\n Division  Value of c is ", c)
 c = b % a
 print ("\n Modulus  Value of c is ", c)
 c = a**b
 print ("\n Exponent  Value of c is ", c)
 a = 9.0
 b = 2.0
 c = a//b
 print ("\n Floor Dvision  Value of c is ", c)

Python Comparison (Relational) Operators :
These operators compare the values on either sides of them and decide the relation among them. They are also called Relational operators. Assume variable a = 10 and variable b = 20, then :
Operators 
Description 
Example 
== 
If the values of two operands are equal, then the condition becomes true. 
(a == b) is not true. 
!= 
If values of two operands are not equal, then condition becomes true. 
(a != b) is true. 
> 
If the value of left operand is greater than the value of right operand, then condition becomes true. 
(a > b) is not true. 
< 
If the value of left operand is less than the value of right operand, then condition becomes true. 
(a < b) is true. 
>= 
If the value of left operand is greater than or equal to the value of right operand, then condition becomes true. 
(a >= b) is not true. 
<= 
If the value of left operand is less than or equal to the value of right operand, then condition becomes true. 
(a <= b) is true. 
Example :
 a = 10
 b = 20
 if ( a == b ):
 print ("(=)  a is equal to b")
 else:
 print ("(=)  a is not equal to b")
 if ( a != b ):
 print ("(!=)  a is not equal to b")
 else:
 print ("(!=)  a is equal to b")
 if ( a < b ):
 print ("(<)  a is less than b")
 else:
 print ("(<)  a is not less than b")
 if ( a > b ):
 print ("(>)  a is greater than b")
 else:
 print ("(>)  a is not greater than b")
 a = 50;
 b = 20;
 if ( a <= b ):
 print ("(<=)  a is either less than or equal to b")
 else:
 print ("(<=)  a is neither less than nor equal to b")
 if ( b >= a ):
 print ("(>=)  b is either greater than or equal to b")
 else:
 print ("(>=)  b is neither greater than nor equal to b")

Python Assignment Operators :
Assume variable a = 10 and variable b = 20, then :
Operators 
Description 
Example 
= 
Assigns values from right side operands to left side operand 
c = a + b assigns value of a + b into c 
+= Add AND 
It adds right operand to the left operand and assign the result to left operand 
c += a is equivalent to c = c + a 
= Subtract AND 
It subtracts right operand from the left operand and assign the result to left operand 
c = a is equivalent to c = c  a 
*= Multiply AND 
It multiplies right operand with the left operand and assign the result to left operand 
c *= a is equivalent to c = c * a 
/= Divide AND 
It divides left operand with the right operand and assign the result to left operand 
c /= a is equivalent to c = c / ac /= a is equivalent to c = c / a 
%= Modulus AND 
It takes modulus using two operands and assign the result to left operand 
c %= a is equivalent to c = c % a 
**= Exponent AND 
Performs exponential (power) calculation on operators and assign value to the left operand 
c **= a is equivalent to c = c ** a 
//= Floor Division 
It performs floor division on operators and assign value to the left operand 
c //= a is equivalent to c = c // a 
Example :
 a = 10
 b = 20
 c = 0
 c = a + b
 print ("Assigns values  Value of c is ", c)
 c += a
 print ("Add AND  Value of c is ", c)
 c = a
 print ("Subtract AND  Value of c is ", c)
 c *= a
 print ("Multiply AND  Value of c is ", c)
 c /= a
 print ("Divide AND  Value of c is ", c)
 c = 2
 c %= a
 print ("Modulus AND  Value of c is ", c)
 c **= a
 print ("Exponent AND  Value of c is ", c)
 c //= a
 print ("Floor Division  Value of c is ", c)

Python Bitwise Operators :
Bitwise operator works on bits and performs bit by bit operation. Assume if a = 60 and b = 13 Now in binary format they will be as follows :
a = 0011 1100
b = 0000 1101
Operators 
Description 
Example 
& Binary AND 
Operator copies a bit to the result if it exists in both operands 
(a & b) (means 0000 1100) 
 Binary OR 
It copies a bit if it exists in either operand 
(a  b) = 61 (means 0011 1101) 
^ Binary XOR 
It copies the bit if it is set in one operand but not both 
(a ^ b) = 49 (means 0011 0001) 
~ Binary Ones Complement 
It is unary and has the effect of 'flipping' bits 
(~a ) = 61 (means 1100 0011 in 2's complement form due to a signed binary number 
<< Binary Left Shift 
The left operands value is moved left by the number of bits specified by the right operand 
a << 2 = 240 (means 1111 0000) 
>> Binary Right Shift 
The left operands value is moved right by the number of bits specified by the right operand 
a >> 2 = 15 (means 0000 1111) 
Example :
 a = 60 #60 = 0011 1100
 b = 13 #13 = 0000 1101
 c = 0
 c = a & b; #12 = 0000 1100
 print ("Binary AND  Value of c is ", c)
 c = a  b; #61 = 0011 1101
 print ("Binary OR  Value of c is ", c)
 c = a ^ b; #49 = 0011 0001
 print ("Binary XOR  Value of c is ", c)
 c *= a
 print ("Multiply AND  Value of c is ", c)
 c = ~a; #61 = 1100 0011
 print ("Binary Ones Complement  Value of c is ", c)
 c = a << 2; #240 = 1111 0000
 print ("Binary Left Shift  Value of c is ", c)
 c = a >> 2; #15 = 0000 1111
 print ("Binary Right Shift  Value of c is ", c)

Python Logical Operators :
Assume variable a = 10 and variable b = 20, then :
Operators 
Description 
Example 
and Logical AND 
If both the operands are true then condition becomes true. 
(a and b) is true. 
or Logical OR 
If any of the two operands are nonzero then condition becomes true. 
(a or b) is true. 
not Logical NOT 
Used to reverse the logical state of its operand. 
Not(a and b) is false. 
Example :
 a = 10
 b = 20
 if a and b:
 print("and  true")
 else:
 print("and  false")
 if a or b:
 print("or  true")
 else:
 print("or  false")

Python Membership Operators :
Python’s membership operators test for membership in a sequence, such as strings, lists, or tuples. There are two membership operators as explained below :
Operators 
Description 
Example 
in 
Evaluates to true if it finds a variable in the specified sequence and false otherwise. 
x in y, here in results in a 1 if x is a member of sequence y. 
not in 
Evaluates to true if it does not finds a variable in the specified sequence and false otherwise. 
x not in y, here not in results in a 1 if x is not a member of sequence y. 
( Assume variable a = 10 and variable b = 20 )
Example :
 a = 10
 b = 20
 list = [1, 2, 3, 4, 5, 10 ];
 if ( a in list ):
 print ("(in)  a is available in the given list")
 else:
 print ("(in)  a is not available in the given list")
 if ( b not in list ):
 print ("(not in)  b is not available in the given list")
 else:
 print ("(not in)  b is available in the given list")

Output :
Python Identity Operators :
Identity operators compare the memory locations of two objects. There are two Identity operators explained below :
Operators 
Description 
Example 
is 
Evaluates to true if the variables on either side of the operator point to the same object and false otherwise. 
x is y, here is results in 1 if id(x) equals id(y). 
is not 
Evaluates to false if the variables on either side of the operator point to the same object and true otherwise. 
x is not y, here is not results in 1 if id(x) is not equal to id(y). 
( Assume variable a = 20 and variable b = 20 )
Example :
 a = 20
 b = 20
 if ( a is b ):
 print ("(is)  a and b have same identity")
 else:
 print ("(is)  a and b do not have same identity")
 if ( id(a) == id(b) ):
 print ("(id)  a and b have same identity")
 else:
 print ("(id)  a and b have same identity")
 a = 10
 if ( a is not b ):
 print ("(is not)  a and b do not have same identity")
 else:
 print ("(is not)  a and b have same identity")
