class ReplyKeyboardMarkup(TelegramObject):
"""This object represents a custom keyboard with reply options.
Objects of this class are comparable in terms of equality. Two objects of this class are
considered equal, if their size of :attr:`keyboard` and all the buttons are equal.
Examples:
* Example usage: A user requests to change the bot's language, bot replies to the request
with a keyboard to select the new language. Other users in the group don't see
the keyboard.
* :any:`Conversation Bot <examples.conversationbot>`
* :any:`Conversation Bot 2 <examples.conversationbot2>`
Args:
keyboard (List[List[:obj:`str` | :class:`telegram.KeyboardButton`]]): Array of button rows,
each represented by an Array of :class:`telegram.KeyboardButton` objects.
resize_keyboard (:obj:`bool`, optional): Requests clients to resize the keyboard vertically
for optimal fit (e.g., make the keyboard smaller if there are just two rows of
buttons). Defaults to :obj:`False`, in which case the custom keyboard is always of the
same height as the app's standard keyboard.
one_time_keyboard (:obj:`bool`, optional): Requests clients to hide the keyboard as soon as
it's been used. The keyboard will still be available, but clients will automatically
display the usual letter-keyboard in the chat - the user can press a special button in
the input field to see the custom keyboard again. Defaults to :obj:`False`.
selective (:obj:`bool`, optional): Use this parameter if you want to show the keyboard to
specific users only. Targets:
1) Users that are @mentioned in the :attr:`~telegram.Message.text` of the
:class:`telegram.Message` object.
2) If the bot's message is a reply (has ``reply_to_message_id``), sender of the
original message.
Defaults to :obj:`False`.
input_field_placeholder (:obj:`str`, optional): The placeholder to be shown in the input
field when the keyboard is active;
:tg-const:`telegram.ReplyKeyboardMarkup.MIN_INPUT_FIELD_PLACEHOLDER`-
:tg-const:`telegram.ReplyKeyboardMarkup.MAX_INPUT_FIELD_PLACEHOLDER`
characters.
.. versionadded:: 13.7
Attributes:
keyboard (List[List[:class:`telegram.KeyboardButton` | :obj:`str`]]): Array of button rows.
resize_keyboard (:obj:`bool`): Optional. Requests clients to resize the keyboard.
one_time_keyboard (:obj:`bool`): Optional. Requests clients to hide the keyboard as soon as
it's been used.
selective (:obj:`bool`): Optional. Show the keyboard to specific users only.
input_field_placeholder (:obj:`str`): Optional. The placeholder shown in the input
field when the reply is active.
