Q & A

What are the two types of keyboards mentioned in the script for Telegram bots?

The two types of keyboards mentioned are 'Reply' keyboards and 'Inline' keyboards. 'Reply' keyboards appear at the bottom of the screen instead of the usual phone keyboard, while 'Inline' keyboards are buttons attached to a message.

How do 'Reply' and 'Inline' keyboards differ in functionality?

'Reply' keyboards send their content directly into the chat when a button is pressed, whereas 'Inline' keyboards do not send anything to the chat but perform actions such as sending a request to a server or opening a link or web application within Telegram.

What is the purpose of using 'Inline' keyboards in Telegram bots?

The purpose of using 'Inline' keyboards is to perform actions without sending content directly to the chat, such as sending a callback to the server, opening a link, or interacting with web applications without the user leaving the chat interface.

How can one create a 'Reply' keyboard in a Telegram bot using aiogram?

To create a 'Reply' keyboard in aiogram, one must import 'ReplyKeyboardMarkup' and 'KeyboardButton' from 'aiogram.types', create a 'Keyboard' object, add 'KeyboardButton' objects to it, and then set it as the 'reply_markup' in the message.

What is the significance of the 'resize_keyboard' parameter in 'Reply' keyboards?

The 'resize_keyboard' parameter is used to allow the user to resize the keyboard on their device. It can be set to 'True' to enable resizing or 'False' to keep the keyboard at a fixed size.

How can one add a placeholder to a 'Reply' keyboard button?

A placeholder can be added to a 'Reply' keyboard button using the 'input_field_placeholder' parameter, which sets the placeholder text that appears on the button.

What is the difference between creating a 'Reply' keyboard and an 'Inline' keyboard in aiogram?

The main difference is that 'Inline' keyboards require a URL or a callback to be associated with each button, whereas 'Reply' keyboards do not. 'Inline' keyboards are created using 'InlineKeyboardButton' and are attached to a message using the 'reply_markup' parameter with 'InlineKeyboardMarkup'.

Why might one use a 'Builder' when creating 'Inline' keyboards?

A 'Builder' is used when the content of the keyboard is dynamic, such as when it's based on data retrieved from a database. It allows for the creation of a keyboard with a variable number of buttons without hardcoding the buttons in the code.

How can one create an 'Inline' keyboard dynamically using a 'Builder' in aiogram?

To create an 'Inline' keyboard dynamically, one can use 'InlineKeyboardBuilder' and loop through the data to add 'InlineKeyboardButton' objects with the necessary URL or callback. The 'build' method is then called to finalize the keyboard, which can be set as the 'reply_markup'.

What additional parameters can be set for 'Inline' keyboard buttons?

Additional parameters for 'Inline' keyboard buttons include 'url' for opening a link, 'callback_data' for sending data to the server, 'switch_inline_query' for prompting the user to switch to another inline query, and 'web_app' for opening a web application.

How can one edit an existing 'Inline' keyboard in a Telegram bot?

An existing 'Inline' keyboard can be edited using methods like 'edit_message_reply_markup' with the updated 'InlineKeyboardMarkup'. This allows for dynamic changes to the keyboard based on user interactions or other events.
