Build an Email Simulator - Step 45

Python

Tell us what’s happening:

Can you help me identify where the error in my code lies? I keep getting an error message after running it, which reads: “You should add a print statement in the send_email method that confirms the email was sent.”

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 [{eamil.sender.name}] to [{email.receiver.name}]!\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')

Welcome to the forum @weiw_juan

You do not need to use square brackets in your f-string.

You have a typo, however check how you access sender and receiver names.

Happy coding

I’m having the same issue, same error message:

class User:
    def __init__(self, name):
        self.name = name
        self.inbox = Inbox()

    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 {email.receiver.name}!\n')

```

I also tried email.sender.name instead of self.name. Using Firefox 147.0.2 (aarch64) (“Mozilla/5.0 (Macintosh; Intel Mac OS X 10.15; rv:147.0) Gecko/20100101 Firefox/147.0”) if that’s relevant.

Copying the relevant line from the next exercise worked:

    print(f'Email sent from {self.name} to {receiver.name}!\\n')

Even though the other variations I tried give the same result.

print(f'Email sent from {self.name} to {receiver.name}!\n')
print(f"Email sent from {email.sender.name} to {email.receiver.name}!\n")
print(f'Email sent from {self.name} to {email.receiver.name}!\n')

All output the same thing:

Email sent from b to c!

Is it a bug that it’s not counting the other variations as correct? Or if not, why not?

send_email has parameter receiver so you should use that to get the receiver name

I understand that I can do that, but why is is more correct to access it through ‘receiver’ rather than ‘email.receiver’?
