Question 1: Which of the following statements create a dictionary?
d = {}
d = {“john”:40, “peter”:45}
d = {40:”john”, 45:”peter”}
All of the mentioned
Question 2: What will be the output of the following Python code snippet?
d = {"john":40, "peter":45} print(d)
“john”, 40, “peter”, 45
{‘john’: 40, ‘peter’: 45}
40 and 45
d = (40:”john”, 45:”peter”)
Question 7: Suppose d = {“john”:40, “peter”:45}, to delete the entry for “john” what command do we use?
d.delete(“john”:40)
d.delete(“john”)
del d[“john”]
del d(“john”:40)
Question 8: Suppose d = {“john”:40, “peter”:45}. To obtain the number of entries in dictionary which command do we use?
d.size()
len(d)
size(d)
d.len()
Question 9: What will be the output of the following Python code snippet?
d = {"john":40, "peter":45} print(list(d.keys()))
[“john”, “peter”]
[“john”:40, “peter”:45]
(“john”, “peter”)
(“john”:40, “peter”:45)
Question 10: Suppose d = {“john”:40, “peter”:45}, what happens when we try to retrieve a value using the expression d[“susan”]?
Since “susan” is not a value in the set, Python raises a KeyError exception
It is executed fine and no exception is raised, and it returns None
Since “susan” is not a key in the set, Python raises a KeyError exception
Since “susan” is not a key in the set, Python raises a syntax error
