My code takes input from the user and creates a receipt with the information the program receives from the user:import easyguiitems = []prices = []amount = []amounts = 0finished = Falsetotal_price = 0.00list_num = -1def take_item():    global list_num, amounts, finished    item = easygui.enterbox(What item is it?)    if item == done or item == None:        finished = True    else:        how_many = easygui.integerbox(How many {0:} do you have?.format(item))        amounts = how_many        items.append(item)        amount.append(how_many)        list_num += 1def pricing():    global list_num, total_price    if finished:        pass    else:        try:            price = easygui.enterbox(What is the price of 1 {0:}.format(items[list_num]))        new_price = float(price)        except ValueError:            easygui.msgbox(Please enter a number.)            pricing()        else:            total_price += float(price) * amounts            prices.append(new_price)def create_receipt():    print Item \t Amount \t Price \t Total Price    for i in range(0, list_num+1):        print items[i], \t\t, amount[i], \t\t 3, prices[i]    print \t\t\t , $,total_price    print Thank you for using Tony's Receipt Maker!    print -----------------------------------------------------------while 1:    take_item()    pricing()    if finished:        create_receipt()    else:        continueAre there any ways to improve the efficiency of the code and shorten it? Is there anything I should improve in my code?
