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)
    raise CommunicationError('An error occurred attempting to connect to Twitter. Please try again!')

It looks like you just forgot to put the "except" line between the call to "tweet" and the "raise".

except CommunicationError:

There will always be at least one "except" to go with a "try".
