def save_transaction(price, credit_card, description):

file = open("transactions.txt", "a")

file.write("%07d%16s%16s\n" % (price * 100, credit_card, description))

file.close()

items = ["WORKOUT", "WEIGHTS", "BIKES"]

prices = [35.0, 10.0, 8.0]

running = True

while running:

option = 1

for choice in items:

print(str(option) + ". " + choice)

option = option + 1

print(str(option) + ". Quit")

choice = int(input("Choose an option: "))

if choice == option:

running = False

else:

credit_card = input("Credit card number: ")

save_transaction(prices[choice - 1], credit_card, items[choice - 1])
