# Python Arithmetic Operators Example

Advertisements

Following table shows all the arithmetic operators supported by Python language. 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 will give 30 |

- | Subtraction - Subtracts right hand operand from left hand operand | a - b will give -10 |

* | Multiplication - Multiplies values on either side of the operator | a * b will give 200 |

/ | Division - Divides left hand operand by right hand operand | b / a will give 2 |

% | Modulus - Divides left hand operand by right hand operand and returns remainder | b % a will give 0 |

** | Exponent - Performs exponential (power) calculation on operators | a**b will give 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 is equal to 4 and 9.0//2.0 is equal to 4.0 |

## Example:

Try the following example to understand all the arithmetic operators available in Python programming language:

#!/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
