Part 1: Sin Tax Syntax [NEW PROBLEM] Complete the function sin_tax, which computes and returns the total cost to purchase several items, some of which might be subject to sin taxes. The function takes three arguments: items: a list of items to purchase (strings). If an item appears more than once, this means we want to buy it more than once. prices: a dictionary that maps an item (string) to its price (float) • tax rates: a dictionary that maps an item (string) to its sin tax rate (float). The rate is given as a decimal (e.g., 0.08 to represent 8%). ● If an item from items does not appear in tax rates, then that item is not subject to a sin tax. Assume that every string in items is a valid key in prices. Example #1: items: ['beer', 'wine', 'cigarettes'] prices {'beer': 18.95, 'cigarettes': 12, "wine': 20.0} tax rates: {'beer': 0.03, 'cigarettes': 0.1, 'wine': 0.05) 53.72 Returned: Example #2: items: ['wine', 'beer', 'wine', 'cigarettes', 'wine'] prices: {'beer': 15.5, 'cigarettes': 13, soda': 8.0, 'wine': 25.0} tax rates: {'beer': 0.035, 'cigarettes': 0.12, 'wine' : 0.07} Returned: 110.85
