``None`` to retrieve all dialogs. Note that this may take

offset_peer (:tl:`InputPeer`, optional):

|
|
ignore_migrated (`bool`, optional):

Whether :tl:`Chat` that have ``migrated_to`` a :tl:`Channel`

If set to a folder number like ``1``, only those from

said folder will be returned.

By default Telegram assigns the folder ID ``1`` to

archived chats, so you should use that if you need

to fetch the archived dialogs.

archived (`bool`, optional):

Arguments

The total timeout (in seconds) to use for the whole

timeouts. After these many seconds pass, subsequent
|
|
actions will result in ``asyncio.TimeoutError``.

|
max_messages (`int`, optional):

specified chat, subsequent actions will result in

|
``ValueError``.
|
|
|
|
exclusive (`bool`, optional):
|
|
By default, conversations are exclusive within a single
|
|
chat. That means that while a conversation is open in a

|
chat, you can't open another one in the same chat, unless
|
|
you disable this flag.
|
|
|
|
If you try opening an exclusive conversation for
|
|
a chat where it's already open, it will raise

``AlreadyInConversationError``.

replies_are_responses (`bool`, optional):

If the setting is enabled, calls to `conv.get_response
|
|
<telethon.tl.custom.conversation.Conversation.get_response>`

|
|
<telethon.tl.custom.conversation.Conversation.get_reply>`
|
|
will return different messages, otherwise they may return
|
|
the same message.
|
|
|
|
Consider the following scenario with one outgoing message,
|
|
1, and two incoming messages, the second one replying::
|
|
|
|
Hello! <1
|
|
2> (reply to 1) Hi!
|
|
3> (reply to 1) How are you?

|
msg1 = await conv.send_message('Hello!')
|
|
msg2 = await conv.get_response()
|
|
msg3 = await conv.get_reply()
|
|
|
|
With the setting enabled, ``msg2`` will be ``'Hi!'`` and
|
|
``msg3`` be ``'How are you?'`` since replies are also
|
|
responses, and a response was already returned.
|
|
|
|
With the setting disabled, both ``msg2`` and ``msg3`` will
|
|
be ``'Hi!'`` since one is a response and also a reply.
|
|
|
|
Returns
|
|
A `Conversation <telethon.tl.custom.conversation.Conversation>`.
|
|
|
|
Example
