**Operators** are the symbols which perform the operation on the some values. These values are known as operands. Python have following operators –

- Arithmetic Operators
- Relational Operators
- Assignment Operators
- Logical Operators
- Membership Operators
- Identity Operators
- Bitwise Operators

**1. Arithmetic Operators**

Operator |
Operator Name |
Description |
Example |

+ | Addition | Perform Addition | I=40, J=20I+ J = 60 |

– | Subtraction | Perform Subtraction | I=40, J=20I – J = 20 |

* | Multiplication | Perform Multiplication | I=40, J=20I * J = 800 |

/ | Division | Perform Division and display the | I=30, J=20I /J = 2.5 |

% | Modulus | Return the remainder after Division | I=40, J=20I /J = 0 |

** | Exponent | Performs exponential (power) calculation | I=40, J=20I /J = 20 to the power of 40 |

// | Floor Division | Perform division then remove the decimal value and return Quotient value | I=30, J=20I//J = 1 |

**2. Relational Operators**

It is also known as comparison operator because it compares the values. After comparison it returns the Boolean value i.e. either true or false.

Operator |
Operator Name |
Description |
Example |

== | Equal to | If the values of two operands are equal then then it returns true. | I = 20, J = 20(I == J) is true |

!= | Not Equal to | If the values of two operands are not equal then it returns true. | I = 20, J = 20(I == J) is False |

< | Less than | If the value of left operand is less than the value of right operand then it returns true | I = 40, J = 20(I < J) is False |

> | Greater than | If the value of left operand is greater than the value of right operand then it returns true | I = 40, J = 20(I > J) is True |

<= | Less than or equal to | If the value of left operand is less than or equal to the value of right operand then it returns true. | I = 40, J = 20(I <= J) is False |

>= | Greater than or equal to | If the value of left operand is greater than or equal to the value of right operand then it returns true. | I = 40, J = 20(I >= J) is True |

<> | Not equal to(similar to !=) | If values of two operands are not equal then condition becomes true. | I=40, J = 20(I <> J) is true. This is similar to != operator. |

**3. Assignment Operators**

Operator |
Operator Name |
Description |
Example |

= | Assignment | It assigns value from right side operand to left side operand | I = 40It assigns 40 to I |

+= | Add then assign | It performs addition and then result is assigned to left hand operand | I+=J that meansI = I + J |

-= | Subtract then assign | It performs subtraction and then result is assigned to left hand operand | I-=J that meansI = I – J |

*= | Multiply the assign | It performs multiplication and then result is assigned to left hand operand. | I*=J that meansI = I * J |

/= | Divide then assign | It performs division and then result is assigned to left hand operand | I/=J that meansI = I / J |

%= | Modulus then assign | It performs modulus and then result is assigned to left hand operand | I%=J that meansI = I % J |

**= | Exponent then assign | It performs exponent and then result is assigned to left hand operand | I**=J that meansI = I ** J |

//= | Floor division then assign | It performs floor division and then result is assigned to left hand operand | I//=J that meansI = I // J |

**4. Logical Operators**

Operator |
Operator Name |
Description |
Example |

and | Logical AND | When Both side condition is true the result is true otherwise false | 2<1 and 2<3False |

or | Logical OR | When at least one condition is true then result is true otherwise false | 2<1 or 2<3True |

not | Logical NOT | Reverse the condition | Not(5>4)False |

**5. Membership Operators**

Operator |
Description |
Example |

in | It returns true if it finds a variable in the sequence otherwise returns false | List = [1,2,3,4,5,6,7,8];i=1;If(i in List):print ‘i is available in list’Elseprint ‘i is not available in list’Output – i is available in list |

not in | It returns true if it does not find a variable in the sequence otherwise returns false | List = [1,2,3,4,5,6,7,8];j=10;If(j not in List):print ‘j is not available in list’Elseprint ‘j is available in list’Output – j is not available in list |

**6. Bitwise Operators**

It performs bit by bit operation. Suppose there are two variable I = 10 and J = 20 and their binary values are

I = 10 = 0000 1010

J = 20 = 0001 0100

Operator |
Operator Name |
Description |
Example |

& | Binary AND | If both bits are 1 then 1 otherwise 0 | I & J0000 0000 |

| | Binary OR | If one of the bit is 1 then 1 otherwise 0 | I | J0001 1110 |

^ | Binary XOR | If both bit are same then 0 otherwise 1 | I ^ J0001 1110 |

~ | Binary Complement | If bit is 1 the make it 0 and if bit is 0 the make it 1 | ~I1111 0101 |

<< | Binary Left Shift | The left operands is moved left by the number of bits specified by the right operand. | I << 2 will give 240 i.e. 1111 0000 |

>> | Binary Right Shift | The left operands is moved right by the number of bits specified by the right operand. | I >> 2 will give 15 i.e. 1111 |

**7. Identity Operators**

These operators are used to compare the memory address of two objects.

Operator |
Description |
Example |

is | It returns true if both operand ‘s identity is same otherwise false | I = 20J = 20If(I is J):print ‘I and J have same identity’Elserint ‘I and J have not same identity’Output – I and J have same identity |

is not | It returns true if both operand ‘s identity is not same otherwise false | I = 20J = 230If(I is not J):print ‘I and J have not same identity’Elseprint ‘I and J have same identity’Output – I and J have not same identity |
