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

Can you please help control that messaging to the user of our application? If there is a CommunicationError raised can

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,
)

try:
    message = input("What would you like to tweet?  ")
    raise CommunicationError (""An error occurred attempting to connect to Twitter. Please try again!"")

except Exception as err:
    print(err)
tweet(message)

Hey Praise Mupani, it appears you are adding more complexity than required.

The second task asks to handle any CommunicationError that may occur. The basic format of a try/execpt statment works here. The original task:

tweet(message)

The general form for wrapping error prone code in a try/except statement:

try:
    tweet(message)
except ErrorTypeYouAreTryingToHandle:
    pass  # The handling action you wish to happen, such as print
except ADifferentErrorTypeToHandleIfNeeded:
    pass  # A different handling action you wish to happen, such as print
  • :point_right: replace the fake error types with the ones you need
  • :point_right: replace pass statements with the actions you need

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