Python Practice Creating and Using Functions in Python Practice Functions Use an External Function

What am I doing wrong?

I'm trying to complete Challenge Task 2 of "Practice Creating and Using Fuctions in Python." Please help.

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,
)
try:
    tweet("Hello this is my tweet")

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


message = input("What would you like to tweet?  ")
tweet(message)

Hello Angela Anders How you're doing? :D You have some problems in the code. First you need to put you're tweet function inside a try block because you want to try to tweet first and if there is a problem with the connection you will excpet the CommunicationError. You always want to put the piece of code that may fail for some reason in the try block and then catch the exact exception if the code inside the try block failed. Delete you're current code inside the try block.

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

i hope u understand my answer :]
