# Python 105: Familiarize Yourself with Python Operators

Welcome to Python 105: Familiarize yourself with **Python Operators**. We just finished Python 104: Working with Strings. In this tutorial, you will learn how to work with **python operators.**

### What are Python Operators Used For?

Operators are used to perform operations on variables and values.

Groups of Python Operators

Python divides the operators in the following groups:

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

Let’s dive into each of the above groups of python operators.

## Python Arithmetic Operators

Arithmetic operators are used with numeric values to perform common mathematical operations:

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 to variables:

Operator | Example | Same As | |

= | x = 5 | x = 5 | |

+= | x += 3 | x = x + 3 | |

-= | x -= 3 | x = x – 3 | |

*= | x *= 3 | x = x * 3 | |

/= | x /= 3 | x = x / 3 | |

%= | x %= 3 | x = x % 3 | |

//= | x //= 3 | x = x // 3 | |

**= | x **= 3 | x = x ** 3 | |

&= | x &= 3 | x = x & 3 | |

|= | x |= 3 | x = x | 3 | |

^= | x ^= 3 | x = x ^ 3 | |

>>= | x >>= 3 | x = x >> 3 | |

<<= | x <<= 3 | x = x << 3 |

## Python Comparison Operators

Comparison operators are used to compare 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 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) |

## Python Identity Operators

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 |

## Python Membership Operators

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 |

## Python Bitwise Operators

Logical operators are used to combine conditional statements:

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 |
