python external function practice

Help Please...What am I missing??

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!")

Got it, I had it as an argument and not a string but it wasn't passing either. Changed it back to an argument and removed task one, i.e placed it as the "try statement" and it passed. Thank YOU

You are very close. When working on Task 2, you need to incorporate your solution from Task 1. That is, the standalone tweet(message) from Task 1 should be inside the try statement of Task 2. It's looks like you did have a tweet inside of the try, but it is using the argument string "message* instead of the variable message.

Post back if you need more help. Good luck!!

Donald Lobree, the task 1 solution is interfering with the talks two solution. For task 2, remove the line: tweet(message)

Also, while syntactically acceptable, the print statement after the exception should be on a new line.

Why isn't this answer working?

Thank you,
