Help Formatting Print Statement (input from 3 lists) X 2

[Hebruiser]

I am working on my class project and am having some difficulty getting my print statement to format "neatly". Teacher wants it to look like this when it prints-- ex.'TrapperKeeper________$3.99________13' So, 'product', 'price' and 'quantity'

I am also having similar issues formatting the text I am saving in the .txt file at the end (want to have each field separated by a ' : ')

Here is the code for the first issue:

def calculateTotal(products, prices, item_nums, quantity):
        subtotal = 0
        partial_summary = ''
        order_total = 0
        print()

        print('Items ordered list')
        print('------------------')
        width = 6
        a = 0
        b = 0
        t = len(item_list)

        while b < t:
            qty = float(quantity_list[b])
            a = int(item_list[b])
            price = float(prices[a])
            subtotal = (qty * price)
            order_total = order_total + subtotal
            print(products[b], '\t\t\t', '$', prices[a], '\t\t', quantity)
            b = b + 1

And this is the save to file script, which is ugly, but functional. I just need it to format more neatly as well. I have always had trouble with formatting things to actually look readable and nice, which may be my project over the holidays.

def data_save():
        fileWrite = open('OrdersArchive.txt', 'a')
        fileWrite.write(str(now))
        fileWrite.write(str(cust_name))
        fileWrite.write(str(street))
        fileWrite.write(str(city))
        fileWrite.write(str(state))
        fileWrite.write(str(zipcode))
        fileWrite.write(str(order_summary))
        fileWrite.write(str(order_total))
        print()
        return ()
        data_save()
