# Python Operators

Python operators are used to perform operations on variables and values.

Python operators are as follow:

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

Operator | Name | Example |

+ | Addition | 2 + 2 |

- | Subtraction | 2 - 2 |

* | Multiplication | 2 * 2 |

/ | Division | 2 / 2 |

% | Modulus | 5 % 2 |

** | Exponentiation | 2 ** 2 |

// | Floor division | 2 // 2 |

Assignment operators are used to assign values to variables

Operator | Example | Same 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 |

Comparison operators are used to compare two values

Operator | Name | Example |

== | Equal | 2 == 2 |

!= | Not equal | 2 != 3 |

> | Greater than | 2 > 1 |

< | Less than | 2 < 3 |

>= | Greater than or equal to | 2 >= 3 |

<= | Less than or equal to | 2 <= 1 |

Logical operators are used to combine conditional 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) |

Identity operators are used to compare the objects, not if they are equal, but if they are actually the same object, with the same 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 |

Membership operators are used to test if a sequence is presented in an object

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 |

Bitwise operators are used to compare (binary) numbers:

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 |
