I believe my code is correct for the required output. Not sure why it is still not accepting my message

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

def tweet(words):
    print (words)

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

You made a slight mistake. It has to be in one print statement not two. And you don't need to define the tweet function as they have done it for you, you only need to call it.

I had alot of trouble with this exercise, because I feel that its not clear what the message needed to be. Below are the Solutions to pass all three.

########1st #################
from twitter import (
    tweet,
    MessageTooLongError,
    CommunicationError,
)

message="Hello, World"

try:
    tweet(message)
except CommunicationError:
    print("")
except MessageTooLongError:
    print("")



########## 2nd ###############

from twitter import (
    tweet,
    MessageTooLongError,
    CommunicationError,
)

#message="Hello, World"
message = input("What would you like to tweet?  ")

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


########### 3rd #################




from twitter import (
    tweet,
    MessageTooLongError,
    CommunicationError,
)

#message="Hello, World"
message = input("What would you like to tweet?  ")

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