Grading guidelines for question 2.

2.a)

2 p: The answer gives the output of the program as "[[1, 2, 3, 4],
'abc']", or explains the difference between shallow and deep copy, and
shows what the output would be in either case.

1 p: The answer describes most of the program correctly, but either
gives the wrong output (usually either "[[1, 2, 3], 'abc']" or "[[1,
2, 3, 4], 'def']), or none at all.


2.b)

3 p: The program demonstrates the attribute lookup order in the
following sense: given the source code of the program and the output
of the program, we can deduce precisely which ordering (of the six
possible orderings) between instance, class and base class attributes
is used during the lookup process.

2 p: The program demonstrates either that classes attributes are
searched before base class attributes, or that instance attributes are
searched before class attributes, but not both.

1 p: The program demonstrates that attributes are looked up both from
classes and instances and/or base classes, but gives no indication
about the order of the search.

+1 p: There is a correct verbal description about the lookup
order. This bonus cannot raise the score above 2.
