The list methоd .index(pаttern) cоnsumes а pаttern (an int) and prоduces an integer indicating the position of the pattern in the list. Use the above method to implement a function called find_zipcode that consumes a list of integers representing zipcodes and the number to search for representing the zipcode. The function should return the position of the zipcode in the list. If the zipcode is not in the list, the function should return None. If you accidently erase the unit tests, you can copy them from here. assert_equal(find_zipcode([84095,84118,84043,84015,84404],84404),4)assert_equal(find_zipcode([],84409),None)
