Tell us what’s happening:
Hello, this is more of a curiosity question as I’ve already found the solution.
Why does {receiver} cause such a weird answer in the terminal? As far as I can tell, the receivers name is passed in as an input to the send_email method.
Your code so far
import datetime
class Email:
def __init__(self, sender, receiver, subject, body):
self.sender = sender
self.receiver = receiver
self.subject = subject
self.body = body
self.timestamp = datetime.datetime.now()
self.read = False
def mark_as_read(self):
self.read = True
def display_full_email(self):
self.mark_as_read()
print('\n--- Email ---')
print(f'From: {self.sender.name}')
print(f'To: {self.receiver.name}')
print(f'Subject: {self.subject}')
print(f"Received: {self.timestamp.strftime('%Y-%m-%d %H:%M')}")
print(f'Body: {self.body}')
print('------------\n')
def __str__(self):
status = 'Read' if self.read else 'Unread'
return f"[{status}] From: {self.sender.name} | Subject: {self.subject} | Time: {self.timestamp.strftime('%Y-%m-%d %H:%M')}"
class User:
def __init__(self, name):
self.name = name
self.inbox = Inbox()
# User Editable Region
def send_email(self, receiver, subject, body):
email = Email(sender=self, receiver=receiver, subject=subject, body=body)
receiver.inbox.receive_email(email)
print(f'Email sent from {self.name} to {receiver}!\n')
# User Editable Region
class Inbox:
def __init__(self):
self.emails = []
def receive_email(self, email):
self.emails.append(email)
def list_emails(self):
if not self.emails:
print('Your inbox is empty.\n')
return
print('\nYour Emails:')
for i, email in enumerate(self.emails, start=1):
print(f'{i}. {email}')
def read_email(self, index):
if not self.emails:
print('Inbox is empty.\n')
return
actual_index = index - 1
if actual_index < 0 or actual_index >= len(self.emails):
print('Invalid email number.\n')
return
self.emails[actual_index].display_full_email()
def delete_email(self, index):
if not self.emails:
print('Inbox is empty.\n')
return
actual_index = index - 1
if actual_index < 0 or actual_index >= len(self.emails):
print('Invalid email number.\n')
return
del self.emails[actual_index]
print('Email deleted.\n')
tory = User('Tory')
ramy = User('Ramy')
tory.send_email(ramy, 'Hello', 'Hi Ramy, just saying hello!')
ramy.send_email(tory, 'Re: Hello', 'Hi Tory, hope you are fine.')
