The sum of 6.5 and 6.3 is 12.8

Add Three Numbers With User Input

# Store input numbers
num1 = input('Enter first number: ')
num2 = input('Enter second number: ')
num3 = input('Enter third number: ')

# Add three numbers
sum = float(num1) + float(num2)
 + float(num3)

# Display the sum
print('The sum of {0},{1} and {2} is {3}'.format(num1, num2,num3,sum))
