I keep getting an unexpected indent error in my if statement after calling the tweet function

"""
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?"  )
    if tweet != "Hello this is tweet":
        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 MessageTooLong as err:
    print("An error has occured." ({}).format(err))
