Question

5.Implement a superclass Appointment and subclasses Onetime, Daily and Monthly. An appointment has a description (for example, “see the dentist”) and a date. Write a method occursOn(year,month,day) that checks whether the appointment occurs on that date. For example for a monthly appointment, you must check whether the day of the month matches and the appointment date started before the date entered. Then, fill a list of Appointment objects with a mixture of appointments. Have the user enter a date and print out all appointments that occur on that date. List will be created for you from the data.txt file as your input file and demo-appointment.py for your program that calls your class Appointment.

a) Your code with comments

b) A screenshot of the execution

Test Cases:

Add 2 appointments: Day Month Year Description

1. D 13 6 2010 Jog

2. M 15 1 2012 Haircut

Test 1 for List Function

List: Day Month Year 15 2 2016

Expected Results:

1 1 2013 Do pushups

15 8 2012 Backup important data

13 6 2010 Jog

15 1 2012 Haircut

Test 2 for List Function

4 4 2013

Expected Results:

1 1 2013 Do pushups

4 4 2013 Dentist

Provided Python Program

Currently already

-creates a list from the .txt file

-Asks the user for Add,List,Quit

-Can Add items to the list based on user input

-Functions for List and Save

Still Needs

An Appointment Super-class

Daily,Monthly,OneTime Sub-classes

An occursOn function for each class

A save function for each Class

Integration between the Classes and the List and Save function

def main() :
# Load the list of appointments.
appList = loadAppointments("data.txt")

choice = input("A)dd, L)ist or Q)uit? ").upper()
while choice != "Q" :
if choice == "L" :
listAppointments(appList)
if choice == "A" :
addAppointment(appList)

choice = input("A)dd, L)ist or Q)uit? ").upper()

# Save all of the appointments.
print("Saving appointments to data.txt")

outf = open("data.txt", "w")
for app in appList :
app.save(outf)
outf.close()

## Prompt the user for the information for an appointment and add it to the
# list of appointments.
# @param appList the list of appointments
#
def addAppointment(appList) :
print("Adding a new appointment: ")
day = int(input(" Day? "))
month = int(input(" Month? "))
year = int(input(" Year? "))
desc = input(" Description? ")
app_type = input("O)netime, D)aily or M)onthly? ").upper()

if app_type == "O" :
appList.append(Onetime(day, month, year, desc))
elif app_type == "D" :
appList.append(Daily(day, month, year, desc))
elif app_type == "M" :
appList.append(Monthly(day, month, year, desc))
else :
print("That wasn't a valid appointment type.")

## Ask the user for the day, month and year, then list all appointments on
# the provided date.
# @param appList the list of appointments to search
#
def listAppointments(appList) :
# Read a date from the user and display all of its appointments.
day = int(input("Enter the day: "))
month = int(input("Enter the month: "))
year = int(input("Enter the year: "))

# Find all of the appointments on the entered date.
for app in appList :
if app.occursOn(day, month, year) :
app.printappt()

## Load the appointments from the file whose name is provied.
# @param fname the name of the file to load
#
def loadAppointments(fname) :
# Try to open the file. If that fails, return an empty list of appointments.
try :
inf = open(fname, "r")
except :
return []

# Load all of the appointments from the file, saving them in the list retval.
retval = []
for line in inf :
line = line.strip()
parts = line.split("|")
if parts[0] == "O" :
retval.append(Onetime(int(parts[1]), int(parts[2]), int(parts[3]), parts[4]))
elif parts[0] == "D" :
retval.append(Daily(int(parts[1]), int(parts[2]), int(parts[3]), parts[4]))
elif parts[0] == "M" :
retval.append(Monthly(int(parts[1]), int(parts[2]), int(parts[3]), parts[4]))

# Close the data file.
inf.close()

# Return the list of appointments.
return retval

# Call the main function.
main()

Here is the Text File
