not sure what does TypeError: object of type 'type' has no len() mean?
""" 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?

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

Hi there, CESAR AGUILAR! The
CommunicationError is in itself a class. It is not iterable so the
len() function won't work on it.
You're really close here. Your
tweet(message) was meant to be put inside the
try as it is the thing that could potentially fail. Imagine that you're about to send a tweet when your phone loses connection to the network. That might create a communication error with the server.
try: tweet(message) # try to twee the message except CommunicationError: # this fires if there was a communication error with the server print("An error occurred attempting to connect to Twitter. Please try again!")
Hope this helps!
