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

I've tried everything I'm so confused any advice is helpful at this point.

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
    raise MessageTooLongError("Oh no! Your message was too long")
try:
    tweet(message)
except CommunicationError:
    print("An error occurred attempting to connect to Twitter. Please try again!")
except MessageTooLongError as err:
    print("({})".format(err))

Hi Ariadna,

You almost have the right answer. First, you can take out this line:

    raise MessageTooLongError("Oh no! Your message was too long")

The tweet function is already going to raise errors if there is a problem, so you don't have to do it yourself. All it's asking you to do is to catch the errors in a try... except statement.

Next, that "Oh no..." line has to be added to the except statement, so your last line should read:

    print("Oh no! Your message was too long ({})".format(err))

After that, everything should be working. I hope this helps!

That worked! That part about the function raising the error really helped me understand why it wasn't working! Thanks for your help Louise St. Germain.
