Question

Suppose d = {"john":40, "peter":45}, what happens when retieving a value using d["susan"]?

a) Since "susan" is not a value in the set, Python raises a KeyError exception.

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

c) Since "susan" is not a key in the set, Python raises a KeyError exception.

d) Since "susan" is not a key in the set, Python raises a syntax error.
