Come on man! What Am I doing wrong -

Come on man! What Am I doing wrong -

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

try:
    message

except
    print("Something went wrong")

From the look of this, is it the second part of the coding challenge you are having difficulty with? If so, it is only a few small things missing!

First, in your try block, you only have the variable for "message". On it's own, this can't do anything. The question wants to use the tweet() method on it!

tweet(message)

Second, your except is missing a : after it. However, question two is looking to cover the specific error CommunicationError. Just using "except" will work, but question three will ask you to just do specific anyway, so best prepare for it by looking for specifics now! The way to do that is by following "except" with the error you are looking for, such as CommunicationError. Then the : to start the except block.

I hope this helps!

so change tweet(message) to tweet() ?

No, tweet() was referring to the method to use. tweet(message) is correct! You just currently have only "message".

Hi Anthony Costanza

Your current code:

try:
    message

except
    print("Something went wrong")

They are requesting that you call the tweet function and pass in the message variable. Which with your try block would look like:

try: 
    tweet(message)

except
    print("Something went wrong")

which will pass the first challenge.

The second part will have you create an exception for a specific error, but you are already almost there. :D Keep it up!

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

in the except statement, you have to label the exception
