using external functions

I'm having issues with doing the code challenge. I feel like I'm already including what the hints suggest..

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?  ")

try:
    tweet(message) 
except CommunicationError as commError:
    print("An error occurred attempting to connect to Twitter. Please try again!")
except MessageTooLongError as messError:
    print("Oh no! Your message was too long ({})".format(message))

The challenge is asking you to show the returned error message. You are incorrectly showing the original tweet text.

except MessageTooLongError as messError:
    print("Oh no! Your message was too long ({})".format(message))  # this line is incorrect
