Question

In Python please.

Problem 3 (Tracking Stock Levels)
For this third part, you will add functionality to track stock levels within the store and prevent
customers from placing orders that cannot be fulfilled. Again, copy your solution from the
previous problem into a new file called a2p3.py. Do not overwrite your previous solution, as
the TAs will want to see them both.
Modify your code by adding a new variable to keep track of the stock level of each product in
the store. The initial stock quantity of each product should be 15. Update your menu display to
include the stock levels of each product. Whenever a customer successfully selects a product
and specifies an acceptable amount, the stock level should be decreased by the amount the
customer has selected. If there is not enough stock to fulfill the request, the customer should
receive a message indicating this and the menu should be printed again (similar to an incorrect
input scenario).

Below is a sample run of the program that demonstrates how your output could look (user input
is highlighted for emphasis):
