We'd like to create a Keyboard class that takes in an arbitrary number of Buttons and stores these Buttons in a dictionary. The keys in the dictionary will be ints that represent the position on the Keyboard, and the values will be the respective Button. Fill out the methods in the Keyboard class according to each description, using the doctests as a reference for the behavior of a Keyboard.

class Button:

   """

Explanation:

Represents a single button

   """

   def __init__(self, pos, key):

       """

       Creates a button

       """

       self.pos = pos

       self.key = key

       self.times_pressed = 0

class Keyboard:

   """A Keyboard takes in an arbitrary amount of buttons, and has a

   dictionary of positions as keys, and values as Buttons.

   >>> b1 = Button(0, "H")

   >>> b2 = Button(1, "I")

   >>> k = Keyboard(b1, b2)

   >>> k.buttons[0].key

   'H'

   >>> k.press(1)

   'I'

   >>> k.press(2) #No button at this position

   ''

   >>> k.typing([0, 1])

   'HI'

   >>> k.typing([1, 0])

   'IH'

   >>> b1.times_pressed

   2

   >>> b2.times_pressed

   3

    def __init__(self, *args):

       for in :

     def press(self, info):

       """Takes in a position of the button pressed, and

       returns that button's output"""

       if :

   def typing(self, typing_input):

       """Takes in a list of positions of buttons pressed, and
