Question

Suppose the PYTHON program below is run on your computer:

expenses = 0

while True:

answer = input("Give the price of the next item ordered?")

if answer == "end":

break

else:

price = float(answer)

expenses = expenses + price

print "Total value of orders is:", expenses

What changes would you make to the PYTHON program above so that it is clear that the values are all in pounds?

Answer 1

#Approach 1
#Ask user to enter amount in pounds
expenses = 0
while True:
    #We have to ask user to enter amount in pounds
    answer = input("Give the price of the next item ordered in pounds?")
    if answer == "end":
        break
    else:
        price = float(answer)
    expenses = expenses + price

print("Total value of orders is:", expenses)

===================================

#Approach 2
#Ask user to enter amount in dollars and cnvert the final amount to pounds
expenses = 0
while True:
    #We have to ask user to enter amount in pounds
    answer = input("Give the price of the next item ordered in pounds?")
    if answer == "end":
        break
    else:
        price = float(answer)
    expenses = expenses + price

print("Total value of orders is:", (expenses*0.76))
