# Python Operators

Python Operators are used to perform operations.

For example: you can perform addition of two number here + operator is used.

##### Python has following types of operators.

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

#### Python Arithmetic Operators

Arithmetic operators are used to perform common mathmatical opperations.

Operator | Name | Example |
---|---|---|

+ | Addition | x + y |

- | Subtraction | x - y |

* | Multiplication | x * y |

/ | Division | x / y |

% | Modulus | x % y |

** | Exponentiation | x ** y |

// | Floor division | x // y |

#### Python Assignment Operators

Assignment operators are used to assign values.

Operator | Example | Like as |
---|---|---|

= | x = 2 | x = 2 |

+= | x += 2 | x = x + 2 |

-= | x -= 2 | x = x - 2 |

*= | x *= 2 | x = x * 2 |

/= | x /= 2 | x = x / 2 |

%= | x %= 2 | x = x % 2 |

//= | x //= 2 | x = x // 2 |

**= | x **= 2 | x = x ** 2 |

&= | x &= 2 | x = x & 2 |

|= | x |= 2 | x = x | 2 |

^= | x ^= 2 | x = x ^ 2 |

>>= | x >>= 2 | x = x >> 2 |

<<= | x <<= 2 | x = x << 2 |

#### Python Comparison Operators

Comparison operators are used to compair two values.

Operator | Name | Example |
---|---|---|

== | Equal | x == y |

!= | Not equal | x != y |

> | Greater than | x > y |

< | Less than | x < y |

>= | Greater than or equal to | x >= y |

<= | Less than or equal to | x <= y |

#### Python Logical Operators

Logical operators are generally used for combining two or more relational statements

Operator | Description | Example |
---|---|---|

and | Returns True if both statements are true | x < 5 and x < 10 |

or | Returns True if one of the statements is true | x < 5 or x < 4 |

not | Reverse the result, returns False if the result is true | not(x < 5 and x < 10) |

#### Python Identity Operators

Identity operators are generally used compair two objects and their memory location.

Operator | Description | Example |
---|---|---|

is | Returns True if both variables are the same object | x is y |

is not | Returns True if both variables are not the same object | x is not y |

#### Python Membership Operators

Membership operators are generally used to text whether a sequence present in it or not.

Operator | Description | Example |
---|---|---|

in | Returns True if a sequence with the specified value is present in the object | x in y |

not in | Returns True if a sequence with the specified value is not present in the object | x not in y |

#### Python Bitwise Operators

Bitwise operators are generally used to compair number in binary form.

Operator | Name | Description |
---|---|---|

& | AND | Sets each bit to 1 if both bits are 1 |

| | OR | Sets each bit to 1 if one of two bits is 1 |

^ | XOR | Sets each bit to 1 if only one of two bits is 1 |

~ | NOT | Inverts all the bits |

<< | Zero fill left shift | Shift left by pushing zeros in from the right and let the leftmost bits fall off |

>> | Signed right shift | Shift right by pushing copies of the leftmost bit in from the left, and let the rightmost bits fall off |
