Why is this code not working?

Can someone please explain to me why this code isnt running. I have a try except block set up and dont understand?

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
tweet(message)

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

You should only call the "tweet" function one time, from inside the "try". Just remove the duplicate call that happens before the "try" and you should pass task 2.
