Write a program that accepts three decimal numbers as input and outputs their sum.

i = 0

total = []

print('Enter 3 decimal numbers')

while i < 3:

   num = float(input(str(i+1)+')'))

   i += 1

   total.append(num)

print('sum = ',sum(total))

Explanation:

The programming language used is python.

The code prompts the user to Enter three decimal numbers, accepts the numbers and then outputs the sum.

A WHILE loop is used to collect the three numbers and the numbers are stored in a list using the append method. finally we make use of the list attribute sum, to evaluate the sum of the three numbers inputted.

A picture is attached  for you to see how the code behaves.
