Programming Exercise 4-8

# Declare variables for the number, and the

# total.

number = 1.0 # Initialize for while loop

total = 0.0

# Continue adding numbers while they are positive.

while number > 0:

number = float(input(‘Enter a positive number’ \

‘ (negative to quit): ‘))

# Check that number is positive so as

# not to change value of the total.

if number > 0:

total = total + number

# Display total.

print (‘Total =’, format(total, ‘.2f’))
