class MessageEdited(NewMessage):
"""
Occurs whenever a message is edited. Just like `NewMessage
<telethon.events.newmessage.NewMessage>`, you should treat
this event as a `Message <telethon.tl.custom.message.Message>`.
.. warning::
On channels, `Message.out <telethon.tl.custom.message.Message>`
will be `True` if you sent the message originally, **not if
you edited it**! This can be dangerous if you run outgoing
commands on edits.
Some examples follow:
* You send a message "A", ``out is True``.
* You edit "A" to "B", ``out is True``.
* Someone else edits "B" to "C", ``out is True`` (**be careful!**).
* Someone sends "X", ``out is False``.
* Someone edits "X" to "Y", ``out is False``.
* You edit "Y" to "Z", ``out is False``.
Since there are useful cases where you need the right ``out``
value, the library cannot do anything automatically to help you.
Instead, consider using ``from_users='me'`` (it won't work in
broadcast channels at all since the sender is the channel and
not you).
Example
.. code-block:: python
from telethon import events
@client.on(events.MessageEdited)
async def handler(event):
# Log the date of new edits
print('Message', event.id, 'changed at', event.date)
