Program in Python 3. Thank you!

Homework 5, Linked Lists A greengrocer would like to maintain a linked lists about his products. For each product he saves it name, price and stock amount. Write a program that creates an empty linked list and then prompts to user to do one of the following: 1. Add a product to the list (anywhere) 2. Print all products in the LinkedList 3. Print all products above a certain price 4. Print all low-stock products (Less than 20 pounds) 5. Exit Hint: The trick here is to make a node with 4 parts: one for the produce name, one for the price, one for the stock and one a ref to the next node. class Node: def __init__(self, nm, pr. st): self.name = nm self price = pr self stock = st self.ref = None
