# Python Arithmetic Operators Example

Advertisements

Assume variable a holds 10 and variable b holds 20, then

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

+ Addition | Adds values on either side of the operator. | a + b = 30 |

- Subtraction | Subtracts right hand operand from left hand operand. | a – b = -10 |

* Multiplication | Multiplies values on either side of the operator | a * b = 200 |

/ Division | Divides left hand operand by right hand operand | b / a = 2 |

% Modulus | Divides left hand operand by right hand operand and returns remainder | b % a = 0 |

** Exponent | Performs exponential (power) calculation on operators | a**b =10 to the power 20 |

// | Floor Division - The division of operands where the result is the quotient in which the digits after the decimal point are removed. | 9//2 = 4 and 9.0//2.0 = 4.0 |

## Example

Assume variable a holds 10 and variable b holds 20, then −

#!/usr/bin/python a = 21 b = 10 c = 0 c = a + b print "Line 1 - Value of c is ", c c = a - b print "Line 2 - Value of c is ", c c = a * b print "Line 3 - Value of c is ", c c = a / b print "Line 4 - Value of c is ", c c = a % b print "Line 5 - Value of c is ", c a = 2 b = 3 c = a**b print "Line 6 - Value of c is ", c a = 10 b = 5 c = a//b print "Line 7 - Value of c is ", c

When you execute the above program, it produces the following result −

Line 1 - Value of c is 31 Line 2 - Value of c is 11 Line 3 - Value of c is 210 Line 4 - Value of c is 2 Line 5 - Value of c is 1 Line 6 - Value of c is 8 Line 7 - Value of c is 2
