4. Which of the following statements create a dictionary?
Correct Answer is : All of the mentioned
5. Read the code shown below carefully and pick out the keys? d = {"john":40, "peter":45}
Correct Answer is : “john” and “peter”
6. What will be the output? d = {"john":40, "peter":45}"john" in d
Correct Answer is : TRUE
7. What will be the output? d1 = {"john":40, "peter":45}d2 = {"john":466, "peter":45}d1 == d2
Correct Answer is : FALSE
8. What will be the output? d1 = {"john":40, "peter":45}d2 = {"john":466, "peter":45}d1 > d2
Correct Answer is : Error
9. What is the output? d = {"john":40, "peter":45}d["john"]

10. Suppose d = {“john”:40, “peter”:45}, to delete the entry for “john” what command do we use
Correct Answer is : del d[“john”].
11. Suppose d = {“john”:40, “peter”:45}. To obtain the number of entries in dictionary which command do we use?
Correct Answer is : len(d)
12. What will be the output? d = {"john":40, "peter":45}print(list(d.keys()))
Correct Answer is : [“john”, “peter”].
13. Suppose d = {“john”:40, “peter”:45}, what happens when we try to retrieve a value using the expression d[“susan”]?
Correct Answer is : Since “susan” is not a key in the set, Python raises a KeyError exception
