Solution:

Which of the following matrix definitions will throw an error in Python?

1

A = [[1, 2, 3], [4, 5, 6], [7, 8, 9]]

2

B = [[3, 3, 3], [4, 4, 4], [5, 5, 5]]

3

Solution:

Suppose d = {“john”:40, “peter”:45}, what happens when we try to retrieve a value using the expression d[“susan”]?

1

Since “susan” is not a value in the set, Python raises a KeyError exception

2

It is executed fine and no exception is raised, and it returns None

3

Since “susan” is not a key in the set, Python raises a KeyError exception

4

Since “susan” is not a key in the set, Python raises a syntax error
