In computer programming languages operators are special symbols which represent computations, conditional matching etc. The values the operator uses are called operands.

c = a + b Here a and b are called operands and '+' is an operator

Python supports following operators.

- Arithmetic Operators
- Comparison Operators
- Logical Operators
- Assignment Operators
- Bitwise Operator
- Conditional Operators

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

+ | Addition | x+y | Sum of x and y. |

- | Subtraction | x-y | Difference of x and y. |

* | Multiplication | x*y | Product of x and y. |

/ | Division | x/y | Quotient of x and y. |

% | Modulus | x%y | Remainder of x divided by y. |

** | Exponent | x**y | x**y will give x to the power y |

// | Floor Division | x/ y | The division of operands where the result is the quotient in which the digits after the decimal point are removed. |

See the following statements in Python Shell.

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

== | Equal | x==y | True if x is exactly equal to y. |

!= | Not equal | x!=y | True if x is exactly not equal to y. |

> | Greater than | x>y | True if x (left-hand argument) is greater than y (right-hand argument). |

< | Less than | x<y | True if x (left-hand argument) is less than y (right-hand argument). |

>= | Greater than or equal to | x>=y | True if x (left-hand argument) is greater than or equal to y (left-hand argument). |

<= | Less than or equal to | x<=y | True if x (left-hand argument) is less than or equal to y (right-hand argument). |

See the following statements in Python Shell.

Operator | Example |
Result |
---|---|---|

and | (x and y) | is True if both x and y are true. |

or | (x or y) | is True if either x or y is true. |

not | (x not y) | If a condition is true then Logical not operator will make false. |

See the following statements in Python Shell.

Operator | Shorthand |
Expression |
Description |
---|---|---|---|

+= | x+=y | x = x + y | Adds 2 numbers and assigns the result to left operand. |

-= | x-= y | x = x -y | Subtracts 2 numbers and assigns the result to left operand. |

*= | x*= y | x = x*y | Multiplies 2 numbers and assigns the result to left operand. |

/= | x/= y | x = x/y | Divides 2 numbers and assigns the result to left operand. |

%= | x%= y | x = x%y | Computes the modulus of 2 numbers and assigns the result to left operand. |

**= | x**=y | x = x**y | Performs exponential (power) calculation on operators and assign value to the equivalent to left operand. |

//= | x//=y | x = x//y | Performs floor division on operators and assign value to the left operand. |

See the following statements in Python Shell.

Operator | Shorthand |
Expression |
Description |
---|---|---|---|

& | And | x & y | Bits that are set in both x and y are set. |

| | Or | x | y | Bits that are set in either x or y are set. |

^ | Xor | x ^ y | Bits that are set in x or y but not both are set. |

~ | Not | ~x | Bits that are set in x are not set, and vice versa. |

<< | Shift left | x <<y | Shift the bits of x, y steps to the left |

>> | Shift right | x >>y | Shift the bits of x, y steps to the right. |

# Each step means 'multiply by two'

* Each step means 'divide by two'

Conditional expressions or ternary operator have the lowest priority of all Python operations. The expression x if C else y first evaluates the condition, C (not x); if C is true, x is evaluated and its value is returned; otherwise, y is evaluated and its value is returned.
