The problem I am facing is commented in the code. Thanks for any help in
advance.===============================================================================================================#15
Change Return Program
#The user enters a cost and then the amount of money given. You should write a
#program that works out what denominations of change should be given in pounds,
50p,
#20p, 10p etc.#to do this the programme needs to divide the change ammount by
1.00 then 0.50 then 0.20 untill it reaches zero#Extensions:#1. The program will
figure out the change for the American currency and the number
#of quarters, dimes, nickels, pennies needed for the change
#2. Make an automatic testing part of your program where it automatically
generates a
#random price and an amount that you give the cashier. It then works out what
change to
#give, and then tests that your program works by adding the change back onto
the price of
#the item to prove your program works. It should flag an error if there are
problems.
cost_of_item = int(float(input("how much money does the item
cost?")))money_given = int(float(input("How much money is given?")))change =
(money_given) - (cost_of_item)
#def coin_return(amount):coinvalues = {'£1':1.00, '50p':0.50,
'20p': 0.20, '10p': 0.10, '5p': 0.05, '2p': 0.02,
'1p': 0.0}
while change != 0: coinvalues = {'£1':1.00, '50p':0.50,
'20p': 0.20, '10p': 0.10, '5p': 0.05, '2p': 0.02,
'1p': 0.0} answer = [] for coin_name, coin_value in coinvalues:
#take the maximum value in the dictionary that is not above the variable
#"change" and then append it into the answer list.

# I want to take the max value in the dictionary "coinvalues" #
# that is the same as or lower than the variable "change". #
# I have no Idea how to search through the coinvalues dictionary #
# and find the value that is highest but does not exceed the #
# value held in the variable "change". #
