            Few examples of using Python library - random for random number generation:

            >>> import random
            >>> rollno=[1, 2, 3, 4, 5]
            >>> random.shuffle(rollno)

            >>>print(rollno)
            [1, 3, 2, 4, 5]
            >>> random.shuffle(rollno)
            >>> print(rollno)

            [5, 1, 4, 3, 2]
            >>> random_number = random.randint(1, 10) # Generate a random integer between 1 and
            10 (inclusive)
            >>> print (random_number)
            6
            >>> random_float = random.random() # Generate a random floating-point number between
            0 and 1
            >>> print(round(random_float,2))
            0.81

                 1.  What are python libraries?

                 2.  Who created Matplotlib?


                 3.  What are the points on the graph that represent a data value on a line or scatter chart called?
