Implement the following methods: def addMessage(self, message) - def getMessage(self, index) - def removeMessage(self, index) Write a short program that uses the Message and Mailbox classes by making a Message, printing it and storing it in a Mailbox

Explanation / Answer

#!usr/python/bin

class Message:
    def __init__(self, sender, recipient, text):
         self.s = sender
         self.r = recipient
         self.t = text
    def append(self, line):
        self.t = self.t + "." + line
    def toString(self):
        print("From:",self.s)
        print("To:",self.r)
        print(self.t)

class Mailbox:
    def __init__(self):
         self.l = []

    def addMessage(self, msg):
        self.l.append(msg)

    def getMessage(self, index):
        return self.l[index]

    def deleteMessage(self, index):
        del self.l[index]

x = Message("John", "Harry", "Hi, I am fine")
y = Mailbox()
x.append(" How are you")
x.toString()
y.addMessage(x)
z = Message("","","")
z = y.getMessage(0)
z.toString()
y.deleteMessage(0)
