"""
This object represents one button of the reply keyboard. For simple text buttons String can be
used instead of this object to specify text of the button.
Objects of this class are comparable in terms of equality. Two objects of this class are
considered equal, if their :attr:`text`, :attr:`request_contact`, :attr:`request_location` and
:attr:`request_poll` are equal.
Note:
* Optional fields are mutually exclusive.
* :attr:`request_contact` and :attr:`request_location` options will only work in Telegram
versions released after 9 April, 2016. Older clients will ignore them.
* :attr:`request_poll` option will only work in Telegram versions released after 23
January, 2020. Older clients will receive unsupported message.
Args:
text (:obj:`str`): Text of the button. If none of the optional fields are used, it will be
sent to the bot as a message when the button is pressed.
request_contact (:obj:`bool`, optional): If :obj:`True`, the user's phone number will be
sent as a contact when the button is pressed. Available in private chats only.
request_location (:obj:`bool`, optional): If :obj:`True`, the user's current location will
be sent when the button is pressed. Available in private chats only.
request_poll (:class:`KeyboardButtonPollType`, optional): If specified, the user will be
asked to create a poll and send it to the bot when the button is pressed. Available in
private chats only.
Attributes:
text (:obj:`str`): Text of the button.
request_contact (:obj:`bool`): Optional. The user's phone number will be sent.
request_location (:obj:`bool`): Optional. The user's current location will be sent.
request_poll (:class:`KeyboardButtonPollType`): Optional. If the user should create a poll.
