Question
Python multiple choises please The operation to select a single item from a list is indexing slicing selecting concatentation What is the missing line from the following fragment of code designed to add up the numbers in a list? sum = 0 # missing line sum = sum + x for i in range(len (nums)): for i in range(nums): for x in nums: What is the output from this fragment? myList = [1, "two", "iii", 4] myList [2], "one" print (myList) [1, "two", "one", 4] [1, "two", "one", "iii", 4] [1, "one", "iii", 4] error Suppose myList = [1, 2, 3, 4). Which of the following correctly deletes the value 2 from myList? myList.remove(2) del myList(1) myList.pop(1) all of the above Suppose nums is a list of numbers. Which of the following fragments would put it in order from largest to smallest? nums.sort() nums.pop() reverse(sort(nums)) nums.sort().reverse() nums.sort() nums.reverse() Python lists are different from arrays found in other languages because lists can be accessed by indexing lists grow and shrink as needed lists items can be changed via assignment lists can store a large collection in a single variable What is the output from the following fragment? nums = {1: ' one ', 2: ' two ', 3: ' three '} print(nums [2]) 2 two three errorExplanation / Answer
