Explanation:
The following Python code creates all of the necessary functions in order to request and validate all of the inputs from the user. Once everything is entered and validated it calculates the total fee and outputs it to the user. Also calls the entire class at the end using a test variable...
class Customer:
library_card = 0
patrons_name = ""
patrons_address = ""
type_of_book = ""
book_title = ""
days_overdue = 0
fee = 0.0
book_list = ['paperback regular', 'paperback best seller', 'magazine', 'hardcover']
def __init__(self):
self.library_card = self.get_library_card()
self.patrons_address = input("Patron's Address: ")
self.book_title = input("Book Title: ")
self.type_of_book = self.get_type_of_book()
self.days_overdue = float(self.get_days_overdue())
self.calculate_total()
print("Your total Fee is: " + str(self.fee))
def get_library_card(self):
library_card = int(input("Enter 4-digit library card number: "))
if (type(library_card) == type(0)) and (len(str(library_card)) == 4):
return library_card
else:
print("Invalid Card number:")
self.get_library_card()
def get_type_of_book(self):
type_of_book = input("Type of Book 1-4: ")
if (int(type_of_book) > 0) and (int(type_of_book) <= 4):
return int(type_of_book)
else:
print("Invalid Type")
self.get_type_of_book()
def get_days_overdue(self):
days_overdue = input("Number of Days Overdue: ")
if int(days_overdue) >= 0:
return days_overdue
else:
print("Invalid number of days")
self.get_days_overdue()
def calculate_total(self):
if self.type_of_book == 1:
self.fee = 0.20 * self.days_overdue
if self.fee > 8:
self.fee = 8
elif self.type_of_book == 2:
self.fee = 0.50 * self.days_overdue
if self.fee > 15:
self.fee = 15
elif self.type_of_book == 3:
self.fee = 0.25 * self.days_overdue
if self.fee > 5:
self.fee = 5
else:
self.fee = 0.30 * self.days_overdue
if self.fee > 23:
self.fee = 23
test = Customer()
Answer:
The attached files contain the realization of a D flip-flop from an RS flip-flop. It also contains the truth tables for both kinds of flip-flops
Explanation:
An SR flip flop is like a light switch. Set turns it 'on' and reset turns it 'off'
A D type flip-flop is a clocked flip-flop which has two stable states. A D type flip-flop operates with a delay in input by one clock cycle.
D type flip-flops are easily constructed from an SR flip-flop by simply connecting an inverter between the S and the R inputs so that the input to the inverter is connected to the S input and the output of the inverter is connected to the R input.
