It provides an easy-to-use interface to the ``telegram.Bot`` by caring about getting new updates with the ``Updater`` class from telegram and forwarding them to the ``Dispatcher`` class. We can register handler functions in the ``Dispatcher`` to make our bot react to Telegram commands, messages and even arbitrary updates. - -We'll need an Access Token. **Note:** If you have done this in the previous step, you can use that one. To generate an Access Token, we have to talk to `BotFather `_ and follow a few simple steps (described `here `_). - -First, we create an ``Updater`` object: - -.. code:: python - - >>> from telegram.ext import Updater - >>> updater = Updater(token='token') - -For quicker access to the ``Dispatcher`` used by our ``Updater``, we can introduce it locally: - -.. code:: python - - >>> dispatcher = updater.dispatcher - -Now, we need to define a function that should process a specific type of update: - -.. code:: python - - >>> def start(bot, update): - ... bot.sendMessage(chat_id=update.message.chat_id, text="I'm a bot, please talk to me!") - -We want this function to be called on a Telegram message that contains the ``/start`` command. To do that, we have to use a ``CommandHandler`` object and register it in the dispatcher: - -.. code:: python - - >>> from telegram.ext import CommandHandler - >>> start_handler = CommandHandler('start', start) - >>> dispatcher.add_handler(start_handler) - -The last step is to tell the ``Updater`` to start working: - -.. code:: python - - >>> updater.start_polling() - -Our bot is now up and running (go ahead and try it)! It's not doing anything yet, besides answering to the ``/start`` command. Let's add another handler that listens for regular messages. We're using the `MessageHandler` here to echo to all text messages: - -.. code:: python - - >>> def echo(bot, update): - ... bot.sendMessage(chat_id=update.message.chat_id, text=update.message.text) - ... - >>> from telegram.ext import MessageHandler, Filters - >>> echo_handler = MessageHandler([Filters.text], echo) - >>> dispatcher.add_handler(echo_handler) - -Our bot should now reply to all text messages that are not a command with a message that has the same content. - -Let's add some functionality to our bot. We want to add the ``/caps`` command, that will take some text as parameter and return it in all caps. We can get the arguments that were passed to a command in the handler function: - -.. code:: python - - >>> def caps(bot, update, args): - ... text_caps = ' '.join(args).upper() - ... bot.sendMessage(chat_id=update.message.chat_id, text=text_caps) - ... - >>> caps_handler = CommandHandler('caps', caps, pass_args=True) - >>> dispatcher.add_handler(caps_handler) - -To enable our bot to respond to inline queries, we can add the following (you will also have to talk to BotFather): - -.. code:: python - - >>> from telegram import InlineQueryResultArticle - >>> def inline_caps(bot, update): - ... query = bot.update.inline_query.query - ... results = list() - ... results.append(InlineQueryResultArticle(query.upper(), 'Caps', query.upper())) - ... bot.answerInlineQuery(update.inline_query.id, results) - ... - >>> from telegram.ext import InlineQueryHandler - >>> inline_caps_handler = InlineQueryHandler(inline_caps) - >>> dispatcher.add_handler(inline_caps_handler) - -People might try to send commands to the bot that it doesn't understand, so we can use a ``MessageHandler`` with a ``command`` filter to recognize all commands that were not recognized by the previous handlers. **Note:** This handler has to be added last, else it will be triggered before the ``CommandHandlers`` had a chance to look at the update: - -.. code:: python - - >>> def unknown(bot, update): - ... bot.sendMessage(chat_id=update.message.chat_id, text="Sorry, I didn't understand that command.") - ... - >>> unknown_handler = MessageHandler([Filters.command], unknown) - >>> dispatcher.add_handler(unknown_handler) - -If you're done playing around, stop the bot with this: - -.. code:: python - - >>> updater.stop() - -Check out more examples in the `examples folder `_! - ------------ -_`JobQueue` ------------ - -The ``JobQueue`` allows you to perform tasks with a delay or even periodically. The ``Updater`` will create one for you: - -.. code:: python - - >>> from telegram.ext import Updater - >>> u = Updater('TOKEN') - >>> j = u.job_queue - -The job queue uses functions for tasks, so we define one and add it to the queue. Usually, when the first job is added to the queue, it wil start automatically. We can prevent this by setting ``prevent_autostart=True``: - -.. code:: python - - >>> def job1(bot): - ... bot.sendMessage(chat_id='@examplechannel', text='One message every minute') - >>> j.put(job1, 60, next_t=0, prevent_autostart=True) - -You can also have a job that will not be executed repeatedly: - -.. code:: python - - >>> def job2(bot): - ... bot.sendMessage(chat_id='@examplechannel', text='A single message with 30s delay') - >>> j.put(job2, 30, repeat=False) - -Now, because we didn't prevent the auto start this time, the queue will start ticking. It runs in a seperate thread, so it is non-blocking. When we stop the Updater, the related queue will be stopped as well: - -.. code:: python - - >>> u.stop() - -We can also stop the job queue by itself: - -.. code:: python - - >>> j.stop() - ----------- -_`Logging` ----------- - -You can get logs in your main application by calling `logging` and setting the log level you want: - -.. code:: python - - >>> import logging - >>> logger = logging.getLogger() - >>> logger.setLevel(logging.INFO) + logger = logging.getLogger() + logger.setLevel(logging.INFO) If you want DEBUG logs instead: .. code:: python - >>> logger.setLevel(logging.DEBUG) + logger.setLevel(logging.DEBUG) ================ _`Documentation` ================ -``python-telegram-bot``'s documentation lives at `Read the Docs `_. +``python-telegram-bot``'s documentation lives at `pythonhosted.org `_. =============== _`Getting help` @@ -459,10 +180,12 @@ _`Getting help` You can get help in several ways: 1.
