I wrote the exception line and outputted a message and still not working

using_a_function.py
"""
This is importing a function named `tweet` from a file
    that we unfortunately don't have access to change.

You use it like so:
>>> tweet("Hello this is my tweet")

If the function cannot connect to Twitter,
    the function will raise a `CommunicationError`
If the message is too long,
    the function will raise a `MessageTooLongError`
"""
from twitter import (
    tweet,
    MessageTooLongError,
    CommunicationError,
)

message = input("What would you like to tweet?  ")
# Your code here
try:
    tweet(message)
except CommunicationError:
    print("An error occurred attempting to connect to Twitter. Please try again!")
except MessageTooLongError:
    print("Oh no! Your message was too long {}".format(message))

You have the right idea, but for Task 3 you're printing something different than what it's asking for. The wording is a little bit confusing, but they're looking for the text raised by the exception. So instead of message, you'll want to use the text from the exception itself.

try:
    tweet(message)
except CommunicationError:
    print("An error occurred attempting to connect to Twitter. Please try again!")
except MessageTooLongError: # try the syntax except Exception as arg:
    print("Oh no! Your message was too long {}".format(message)) # instead of message, try using the arg you grabbed above

Hopefully that helps get you on the right track, but let me know if you have any follow up questions or still feel stuck and we can walk through a solution. Nice work, and happy coding!

The instructions say "The exception has additional messaging" .. so it's not the "message" you need to add to the error, but the additional info from the exception object.

So you'll need to get the exception object (using the "as" keyword) and use it for formatting the output.
