Python Arithmetic operators include operators like Addition, Subtraction, Multiplication, Division, Floor Division, Exponent (or Power), and Modulus. All these Arithmetic operators in Python are binary operators, which means they operate on two operands. The below table shows all the Python Arithmetic Operators with examples.

Python Arithmetic Operators | Operation | Example |
---|---|---|

+ | Addition | 10 + 2 = 12 |

– | Subtraction | 10 – 2 = 8 |

* | Multiplication | 10 * 2 = 20 |

/ | Division | 10 / 2 = 5.0 |

% | Modulus – It returns the remainder after the division | 10 % 2 = 0 (Here remainder is zero). If it is 10 % 3, then it will be 1. |

** | Exponent – It returns the Power of One variable against the other | 10 ** 2 = 100 (It means 10 Power 2 or 10²). |

// | Floor Division – Same as Division but it will return the integer value by flooring the extra decimals | 17 // 3 = 5. If you divide 17 by 3, you get 5.667 and the floor division operator will trim the decimal values and outputs the integer |

## Python Arithmetic Operators Example

For this Python Arithmetic operators example, We are using two variables a and b and their values are 12 and 3. We are going to use these two variables to perform various arithmetic operations in Python programming

>>> a = 12 >>> b = 3 >>> addition = a + b >>> subtraction = a - b >>> multiplication = a * b >>> division = a / b >>> modulus = a % b >>> exponent = a ** b >>> Floor_Division = a // b >>> print("Addition of two numbers 12 and 3 is : ", addition) >>> print("Subtracting Number 3 from 12 is : ", subtraction) >>> print("Multiplication of two numbers 12 and 3 is : ", multiplication) >>> print("Division of two numbers 12 and 3 is : ", division) >>> print("Modulus of two numbers 12 and 3 is : ", modulus) >>> print("Exponent of two numbers 12 and 3 is : ", exponent) >>> print("Floor Division of two numbers 12 and 3 is : ", Floor_Division)

The following Python statement will find the exponent. It means 12 power 3 = 12 * 12 * 12 = 1728

exponent = a ** b

When we are using division ( / ) operator the result will be float or decimal value. If you want to display the output as integer value by rounding the value then use Python Floor Division ( // ) operator

## Python Arithmetic Operators on Strings

In this Python Arithmetic operators example, We are using two variables a and b of string data type. Next, we use these two variables to show the problems we generally face while performing arithmetic operations on String Data type.

>>> a = "Tutorial" >>> b = "Gateway" >>> print(a + b) >>> print(a + " " + b) >>> print(a * 3) >>> print((a + " ")* 3) >>> print(a + 3) >>> print(a + str(3))

TIP: Please be careful with brackets, if you misplace it then you will end up with wrong results.

In this program for Arithmetic operators in python, First, We declared two variables a and b of type string and their values are “Tutorial” and “Gateway”

a = "Tutorial" b = "Gateway"

It displays the output as “TutorialGateway” because when we use ‘+’ operator in between string variables python will concat the two strings

print(a+b)

Inserts the empty space between the two words”Tutorial” and “Gateway”. It means the output will be “Tutorial Gateway”

print(a + " " + b)

Displays Tutorial three times

print(a * 3)

Insert space in between each iteration

print((a + " ")* 3)

It is the interesting part because we are using the ‘+’ operator between string and integer.

print(a + 3)

It will throw an error because python will not convert integer object to string object implicitly. To resolve this, we have to explicitly convert three. Be careful while Concating the String and Integers (Type casting plays a major role here).

print(a + str(3))
