Operators are used to perform operations on any operands. They are used to evaluate different types of expressions and to manipulate the value of operands or variables by performing different type of operations.

There are 7 types of operators:

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

Arithmetic operators are the operators used to perform arithmetic operations on numeric operands like addition, subtraction, multiplication, etc.

Different types of Arithmetic Operators:

Operator | Usage | Description |
---|---|---|

+ | a+b | Add values on either side of the operator. |

- | a-b | Subtracts right hand side operand from left side of operand. |

* | a*b | Multiple values on either side of the operator. |

/ | a/b | Divide left hand side of operand by right hand side of operand. |

% | a%b | Return remainder by dividing left hand side of operand by right hand side of operand. |

** | a**b | Return exponent - left operand raised to the power of right. |

// | a//b | Floor Division - The division of operands where the result is quotient in which digit after decimal point are removed. But if one of the operand is negative then result is floored. |

Let's perform programs on above:

```
>>>3+2
5
>>>5-2
3
>>>2*3
6
>>>9/8
1.125
>>>5%2
1
>>>2**3
8
>>>9//8
1
```

These operators are used to compare the values of operands on either side of this operator. This operator return true or false Boolean values.

Different Comparison operators:

Operator | Usage | Description |
---|---|---|

== | a==b | Return true if the values on either side are equals otherwise false. |

!= | a!=b | Return true if the values on either side are not equals otherwise false. |

> | a>b | Return true if the value of operand on the left side is greater than the value of operand on right side. |

< | a
| Return true if the value of operand on the left side is lesser than the value of operand on right side. |

>= | a>=b | Return true if the value of operand on the left side is greater than or equal to the value of operand on right side. |

<= | a<=b | Return true if the value of operand on the left side is less than or equal to the value of operand on right side. |

Let's perform programs on above:

```
>>>3==2
False
>>>3!=2
True
>>>2<=4
True
```

Assignment operator is used to assign a specific value to a variable.

The equal to (

If we use arithmetic operators (

Let's see some example,

```
>>>x=20
>>>x
20
>>>x+=2
>>>x
22
>>>x-=5
>>>x
17
```

The logical operators are used to perform logical operations and to combine two or more conditions to provide specific results i.e. true or false.

Different logical operators:

Operator | Usage | Description |
---|---|---|

and | x and y | True if both sides of operator are true. |

or | x or y | True if either sidesof operator are true. |

not | not x | True if operator is false. |

Bitwise operator acts on the operands bit by bit.

These operators take one ot two operands.

Some bitwise operators appear to be similar to logical operator but they are not.

Different Bitwise Operator:

Operator | Usage | Description |
---|---|---|

& (Binary AND) | ( a&b) | Operator copies a bit to the result if it coexists in both operands |

| (Binary OR) | ( a|b) | |

^ (Binary XOR) | ( a ^ b) | It copies the bit if it is set in one operand but not both. |

~ (1's complement) | ( ~ a) | It is unary and has the effect of 'flipping' bits. |

< < (Binary Left Shift) | ( a < < 2) | The left operands value is moved left by the number of bits specified by the right operand. |

> > (Binary Right Shift) | ( a > > 2) | The left operands value is moved right by the number of bits specified by the right operand. |

The membership operators are used to test whether a value is in a specific sequence or not like in lists, tuples, string, etc. It returns True or False as output.

Different membership operators are:

Operator | Usage | Description |
---|---|---|

in | x in y | True if the value/operand in the left of the operator is present in the sequence in the right of the operator. |

not in | x not in y | True if the value/operand in the left of the operator is not present in the sequence in the right of the operator. |

The identity operators are used to test whether a variable refers to same value/object or not. It returns True or False as output.

Different Identity Operator:

Operator | Usage | Description |
---|---|---|

is | x is True | True if both the operands refer to the same object. |

is not | x is not True | Evaluates to false if the variables on either side of the operator point to the same object and true otherwise. |
