телеграмм бот - 21.0.1 (реально обновлен)-versatile chatbot platform

Example

A bot that echoes received messages.

Scenario

By adding a `MessageHandler` for text filters, the bot can reply to every text message with the same text. This is implemented using `application.add_handler(MessageHandler(filters.TEXT & ~filters.COMMAND, echo))`, where `echo` is an async function that replies with the original message text.

Example

A bot that provides a help message when the `/help` command is issued.

Scenario

Using a `CommandHandler`, the bot listens for the `/help` command and responds with a predefined message. This is done via `application.add_handler(CommandHandler('help', help_command))`, where `help_command` is an async function that sends the help text.

Example

A bot that provides inline query results.

Scenario

When users type inline queries, the bot can return search results directly in the chat. This is managed with an `InlineQueryHandler`, and requires a function like `inline_query` that processes the query and provides results via `update.inline_query.answer(results)`, where `results` is a list of `InlineQueryResult` objects.

Example

A bot that sends a recurring message every day.

Scenario

Using the `JobQueue`, the bot can schedule tasks that run periodically. For instance, a task that sends a 'Good morning!' message daily can be set up via `job_queue.run_daily(daily_greeting, time(hour=8, minute=0))`, where `daily_greeting` is a function that sends the message.

Example

A bot that manages a multi-step conversation with users.

Scenario

By using the `ConversationHandler`, the bot can guide users through a conversation with multiple states and transitions. For example, an order bot may ask for the user's name, then address, and finally confirm the order. This is implemented with a dictionary mapping states to lists of handlers, like `{ASKING_NAME: [MessageHandler(filters.TEXT, ask_name)], ASKING_ADDRESS: [MessageHandler(filters.TEXT, ask_address)]}`.
