Also, could you please comment/explain what each line of code represents in this question.

Write a function piggyBank that accepts a sequence of "coins" and returns counts of the coins and the total value of the bank.

the coins will be given by a list of single characters, each one of 'Q','D','N',P' , representing quarter, dime, nickel, penny
the function returns a tuple with two items:

a dictionary with counts of each denomination. They should always be listed in the order 'Q','D','N',P'
the total value in whole cents of the amount in the bank

Output for this question is shown in the attached image

>>> piggyBank(['D', 'p', 'Q', 'Q', 'D', 'p', 'p'])
({'Q': 2, 'D': 2, 'N': 0, 'p': 3}, 73)
>>> piggyBank (['D', 'D', 'N', 'N', 'N'])
({'Q': 0, 'D': 2, 'N': 3, 'p': 0}, 35)
>>> piggyBank ( ['P', 'D', 'N', 'p', 'N', 'N', 'N', 'Q', 'D', 'P', 'Q', 'Q', 'D'])
({'Q': 3, 'D': 3, 'N': 4, 'p': 3}, 128)
>>> piggyBank (['D', 'P', 'Q', 'Q', 'D', 'p', 'p'])==({ 'Q': 2, 'D': 2, 'N': 0,
'p': 3}, 73)
True
