Need help with question. Sample output below. Coding language is python.
Copy your solution from the question 1 into a new file and name it a2_q2.py. You must not overwrite your previous solution; the marking TA will want to see both files. You will add code to this new file (a2_q2.py) that allows the following functionalities. The user (customer) can now view the e-list to select items for purchase.
They should be able to select the items by entering the corresponding number from the list. Again, invalid selections should be handled with suitable error messages and the list should be repeated (see sample
outputs below). Once the customer has selected a product, the program should ask how many of that product the customer would like to buy. Your program must make sure that selected products are available in stock, otherwise it should generate error messages and the menu should
be repeated. After every valid selection is made, the current total should be printed, and the stock should be updated on the e-list (see sample outputs below).
When the user completes product selection (i.e., enters 4), it should provide the user with their
receipt. The receipt must show (a) the subtotal, (b) tax amount (13% of the subtotal) and (c) the
total cost of the purchase. See sample outputs below.
Sample output (how it should look like):

- Please give correct code. Thanksarrow_forwardFilename: runlength_decoder.py Starter code for data: hw4data.py Download hw4data.py Download hw4data.pyYou must provide a function named decode() that takes a list of RLE-encoded values as its single parameter, and returns a list containing the decoded values with the “runs” expanded. If we were to use Python annotations, the function signature would look similar to this:def decode(data : list) -> list: Run-length encoding (RLE) is a simple, “lossless” compression scheme in which “runs” of data. The same value in consecutive data elements are stored as a single occurrence of the data value, and a count of occurrences for the run. For example, using Python lists, the initial list: [‘P’,‘P’,‘P’,‘P’,‘P’,‘Y’,‘Y’,‘Y’,‘P’,‘G’,‘G’] would be encoded as: ['P', 5, 'Y', 3, ‘P’, 1, ‘G’, 2] So, instead of using 11 “units” of space (if we consider the space for a character/int 1 unit), we only use 8 “units”.

The second file called functions.py contains all the functions your main code.
