Help Amold write a Python program to compute and print the customer's recelpt, Including the bead code, the
quantity ordered and the total price of that many of those types of beads. In addition, your program should
also compute and print the total price of all beads ordered for that customer's order. Remember to use
formatting and descriptive labels as shown in the sample output.

Besides printing the required output, your program must also write the bead code, the new quantity-on-hand

output file called result_bead_list.txt. For each type of bead, If the quantity on hand Is less than 5,
then the message "ORDER MORE" should be added to the end of the line In the file. NOTE: You may assume
that the customer's order will never result in a negative number of beads remalning, I.e., the order can always
be completely filled).
