Right, so lst1[1] gets you closer to what you want.
Further indexing will get you even closer.
===========
lst2 = lst1[1] removes first line of instructions
printing lst2[1:2] produces essentially the list of students and scores ??
([{u'student ': u'Hannah', u'score': 77}, {u'student ': u'Emily', u'score':
57}, {u'student ': u'Olivia', u'score': 80}, {u'student ': u'Nora', u'score':
70},
lst1 is 1 list of 2 items, both of which are tuples. lst1[1] gives you
the second tuple.
That tuple contains 2 items, the first a string and the second a list.
You want the second item, so that's lst1[1][1].
Each of the items in that list is a dict.
