Python Arithmetic Operators
Python Arithmetic operators are used to perform arithmetical operations like addition, subtraction, multiplication, division, etc, in Python programs. We use these operators in scientific calculations and mathematical expressions.
Python Arithmetic Operators
Python arithmetic operators are as follows:
Python Operator 
Name  Description 
+  Addition Operator  The + operator adds two operands. 
–  Subtraction Operator  The – operator subtracts the right operand from the left operand. z = x – y For example, the value of y is subtracted from the x and then assigned to the variable z.

*  Multiplication Operator  The * operator multiplies two operands. 
/  True Division Operator  The / operator divides the left operand by the right one and returns the result into a float. 
%  Modulus Operator  The % operator returns the remainder of the division of the left operand by the right. 
//  Floor Division Operator  The // operator divides the left operand by the right one and returns results into the whole number adjusted to the left in the number line. 
**  Exponential Operator  The ** operator returns the value of the left operand raised to the power of the right. 
Example
The below program illustrates the use of the arithmetic operators:
# Python Arithmetic Operators program # Python Tutorials  www.TestingDocs.com number1 = input('Enter a number:') number1 = int(number1) number2 = input('Enter a number:') number2 = int(number2) result = number1 + number2 print('Addition =', result) diff = number1  number2 print('Subtraction =', diff) product = number1 * number2 print('Multiplication =', product) truediv = number1 / number2 print('True Division =', truediv) floordiv = number1 // number2 print('Floor Division =', floordiv)
Output
Sample output of the program:
Enter a number:25
Enter a number:7
Addition = 32
Subtraction = 18
Multiplication = 175
True Division = 3.5714285714285716
Floor Division = 3
