1). Files, Lists, and Dictionaries: a). Write a function get_price() that asks the user to input prices for several items. The function first prompts the user to enter how many items he/she wants to record, then asks for the name and the price of each item. The function should store the user's input (names paired with prices) in a dictionary named dict_price. The function should return the dictionary. b). Call the function get_price() to create a dictionary. Then display the dictionary. c). Retrieve the keys in this dictionary (that is, the item names in this case) and put them into a list called item_list. Then write the item names into a txt file; each item should take a new line. d). Retrieve the values in this dictionary (that is, the item prices in this case) and put them into a list called price list. Then display the price list. e). Now we want to record the quantity sold for each item. Please write a function get_quantity() that uses the item_list and prompts the user to enter the quantity that has been sold for each item in this list, and creates a dictionary named dict_quantity, in which item names are paired with quantities. The function should return the dictionary. Then call the function and display the dictionary.
