Python Operators

Doing some operations on values that is through operator.operator is a symbol which  is do some operations on values and gives the output.

The values are known as Operands.

• Operand operations(+,-,*,/) operand output operation(=) operand  

    Like:
1 + 2 = 3

• Here 1 and 3 are Operands and  + (plus) ,= (equal) signs are the operators. They generate the output 9.

Python have some operators :

Let's know about python operators..

List of operators :

1) Arithmetic Operators.
2) Relational Operators.
3) Assignment Operators.
4) Logical Operators.
5) Membership Operators.
6) Identity Operators.
7) Bitwise Operators.

Let's know about in detail....

1) Arithmetic Operators:

• // (Double forward slash sign) It Perform Floor division(gives integer value after division)

Like :
5 // 2 = 2

• + (Plus sign)  It is use to perform  an addition.

Like :
5 + 2 = 7

• - (Minus sign) It is use to perform subtraction

Like :
5 - 2 = 3

• * (star sign) It is use to perform multiplication.

Like :
5 * 2 = 10

• / (single forward slash sign) It is use to perform division

Like :
5 / 2 = 2.5

• % (Modulus sign) To return remainder after division(Modulus)

Like :
10 % 3  = 1

• ** (Two star sign) It is use to perform exponent(raise to power)

Like :
3**3  = 27




2) Relational Operators :

• < Less than :

Like :
1<2
Output : True

• > Greater than :

Like :
1<2
Output : False

• <= Less than or equal to :

Like :
1<=1
Output : True

• >= Greater than or equal to :

Like :
10>=5
       Output : True

• == Equal to :

Like :
1<2
Output : False

• != Not equal to :

Like :
1!=2
Output : True

• < > Not equal to(similar to !=) :

Like :
        1< >2
Output : True
 
 3) Assignment Operators :

• = Assignment :

Like :
a = 10
print a
Output : 10

• /= Divide and Assign : 

Like :
a=10
a/=2
Output : 5

• += Add and assign :

Like :
a=10
a+=2
Output : 12

• -= Subtract and Assign :

Like :
                 a=10
                 a-=2
Output : 8

• *= Multiply and assign :

Like :
a=10
a*=2

Output : 20

• %= Modulus and assign :

Like :
a=10
a%=3

Output : 1

• **= Exponent and assign :

Like :
a=5
a**=2
Output : 25

• //= Floor division and assign

Like :
a=25
a//=2
Output : 12

4) Logical Operators:

• and : Logical AND(When both conditions are true output will be true)
• or : Logical OR (If any one condition is true output will be true)
• not : Logical NOT(Compliment the condition i.e., reverse)

5) Membership Operators:

• in : Returns true if a variable is in sequence of another variable, else false.
• not in : Returns true if a variable is not in sequence of another variable, else false.

6) Identity Operators :

• is   : Returns true if identity of two operands are same, else false
• is not : Returns true if identity of two operands are not same, else false.
