I wish I had a better way to represent "pennies" vs. "penny" but it works. This was a nice challenge to help me learn python. Thanks and keep them coming!
My contribution:
cents = 100
cost = int(round(cents * float(raw_input("Enter the cost: "))))
tendered = int(round(cents * float(raw_input("Enter the amount tendered:
"))))
change = tendered - cost
denominations = [2000, 1000, 500, 100, 50, 25, 10, 5, 1]
money = ['$20.00', '$10.00', '$5.00', '$1.00', 'Fifty Cent Piece',
'Quarter', 'Dime', 'Nickel', 'Penny']
moneys = ['$20.00', '$10.00', '$5.00', '$1.00', 'Fifty Cent Pieces',
'Quarters', 'Dimes', 'Nickels', 'Pennies']
givetocustomer = [0, 0, 0, 0, 0, 0, 0, 0, 0]
lnlen = len(denominations)
lni = 0
while lni <= lnlen - 1:
# floor division yields no decimals and no rounding
givetocustomer[lni] = change // denominations[lni]
# modulus returns remainder
change = change % denominations[lni]
if givetocustomer[lni] > 0:
if givetocustomer[lni] > 1:
print str(givetocustomer[lni]) + ' ' + moneys[lni]
else:
print str(givetocustomer[lni]) + ' ' + money[lni]
lni += 1
