  • To write a Simple Python Program with example. In order to show, we are going to add two numbers using Arithmetic Operators

Simple Python Program to add Two numbers

  • This simple Python program allows the user to enter two values and then add those two numbers and assign the total to variable sum.

Sample Code

# Simple Python program to Add Two Numbers
 
number1 = input(" Please Enter the First Number: ")
number2 = input(" Please Enter the second number: ")
 
# Using arithmetic + Operator to add two numbers
sum = float(number1) + float(number2)
print('The sum of {0} and {1} is {2}'.format(number1, number2, sum))

Analysis

  • Following statements ask the user to enter two integer numbers and stores the user entered values in variables number 1 and number 2
number1 = input(" Please Enter the First Number: ")
number2 = input(" Please Enter the second number: ")

  • Next line, we used Python Arithmetic Operators ‘+’ to add number1 and number2 and then assigned that total to sum.
  • From the below statement you can observe that, we used float type cast to convert the user input values to float.
  • This is because, by default user entered values will be of string type and if we use the + operator in between two string values python will concat those two values instead of adding them
sum = float(number1) + float(number2)

  • Following print statement will print the sum variable as Output (30 + 70= 100).
print('The sum of {0} and {1} is {2}'.format(number1, number2, sum))

  • Alternative way of writing the above code is:
# Simple Python program to Add Two Numbers
 
number1 = float(input(" Please Enter the First Number: "))
number2 = float(input(" Please Enter the second number: "))
 
# Using arithmetic + Operator to add two numbers
sum = number1 + number2
print('The sum of {0} and {1} is {2}'.format(number1, number2, sum))
