"""Get one or more messages that belong to a specific chat.
You can retrieve up to 200 messages at once.
Parameters:
chat_id (``int`` | ``str``):
Unique identifier (int) or username (str) of the target chat.
For your personal cloud (Saved Messages) you can simply use "me" or "self".
For a contact that exists in your Telegram address book you can use his phone number (str).
message_ids (``iterable``, *optional*):
Pass a single message identifier or a list of message ids (as integers) to get the content of the
message themselves. Iterators and Generators are also accepted.
reply_to_message_ids (``iterable``, *optional*):
Pass a single message identifier or a list of message ids (as integers) to get the content of
the previous message you replied to using this message. Iterators and Generators are also accepted.
If *message_ids* is set, this argument will be ignored.
replies (``int``, *optional*):
The number of subsequent replies to get for each message.
Pass 0 for no reply at all or -1 for unlimited replies.
Defaults to 1.
Returns:
:obj:`Message` | :obj:`Messages`: In case *message_ids* was an integer, the single requested message is
returned, otherwise, in case *message_ids* was an iterable, the returned value will be an object containing
a list of messages, even if such iterable contained just a single element.
Raises:
RPCError: In case of a Telegram RPC error.
