Forgive me if I am missing something simple, but this keeps popping an AssertionError """ This is importing a function

Keeps mentioning putting it in a try except block but it is..

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!")

The correct tweet call (the one that uses the message variable) is outside of (and two lines above) the "try" block. It needs to be moved inside the block.

The other tweet call using a string literal and is currently inside the block is not needed and should be removed.
