Objective Questions

.. A mininum of 8 questions here (along with answers)

1. Container-ship of values can be checked in a python dictionary

   a. True

   #. False

Answer: False

2. Container-ship of only keys can be checked in a python dictionary

   a. True

   #. False

Answer: True

3. The value in a dictionary can be

   a. String

   #. Integer

   #. Any data type

   #. None

Answer: Any data type

4. Python lists can be made as a key in dictionaries.

   a. True

   #. False

Answer: False

5. Given a python dictionary ``x = {'a' : 1, 'b' : 2, 'c' : 3, 'd' :

   4}``. When printed using ``print x`` will generate the output in

   the order.  {key-value pair ``'a':1`` identified as a, ``'b':2``

   identified as b and so on}

   a. a, b, c, d

   #. d, c, b, a

   #. a, c, b, d

   #. b, d, a, c

   #. Cannot predict

Answer: Cannot predict

6. The python dictionary ``x = {'a' : ['a', 'b', 'c'], 'b' : (1, 2, 3),

   1 : {1 : 'one', 2 : 'two'}, 10 : {10 : 'ten', 11 : 'eleven'}}`` is

   invalid.

   a. True

   #. False

Answer: False

7. Consider the python dictionary ``x = {'a' : ['a','b','c'], 'b' :

   (1, 2, 3), 1 : {1 : 'one', 2 : 'two'}, 10 : {10 : 'ten', 11 :

   'eleven'}}``. And after applying the code below, what will be the

   output of ``print x['a']``

   ::

      x['a'].extend(['d', 'e'])

      x['a'][3] = x[10]

   a. Code will result in error

   #. ['a', 'b', 'c', {11: 'eleven', 10: 'ten'}, 'e']

   #. {10 : 'ten', 11 : 'eleven'}

   #. {10 : 'ten', 11 : 'eleven', 'a' : ['a', 'b', 'c']}

   #. (1, 2, 3, ['a', 'b', 'c'])

Answer: ['a', 'b', 'c', {11: 'eleven', 10: 'ten'}, 'e']

8. Consider the python dictionary ``x = {'a' : ['a','b','c'], 'b' :

   (1, 2, 3), 1 : {1 : 'one', 2 : 'two'}, 10 : {10 : 'ten', 11 :

   'eleven'}}``. The code ``(1, 2, 3) in x.values()`` will return

   a. True

   #. False

   #. Container-ship of values cannot be checked in dictionaries

   #. The dictionary is invalid

Answer: True
