a. [10] Consider the variable myList as follows: myList = [8, 0, 77, 'a', 'j', 7, 34] What do the following expressions evaluate to? If the evaluation will lead to an error, then write Error myList [5] myList[-1] myList [3:5] myList[2:-2] myList [1] > myList [2] b. [10] Assume that the variable all refers to the dictionary that was created as follows: all = {'b':20, 'a':35, 'c': 40} What do the following expressions evaluate to? If the evaluation will lead to an error, then write Error all['b'] len (all) all.keys () all['a'] > all['c'] all['b' + 'c']
