AssertionError

getting an assertionError when i run my code

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?  ")
tweet(message)
try:
    tweet(message)
except CommunicationError:
    print("An error occurred attempting to connect to Twitter. Please try again!")

You are calling the tweet function twice. There should only be one call and it should be inside the try except block.
