Examples¶
In this section we display small examples to show what a bot written with
python-telegram-bot
looks like.
Some bots focus on one specific
aspect of the Telegram Bot API while others focus on one of the
mechanics of this library. Except for the
rawapibot.py example, they all use the high-level
framework this library provides with the
telegram.ext
submodule.
All examples are licensed under the CC0 License and are therefore fully dedicated to the public domain. You can use them as the base for your own bots without worrying about copyrights.
Do note that we ignore one pythonic convention. Best practice would
dictate, in many handler callbacks function signatures, to replace the
argument context
with an underscore, since context
is an unused
local variable in those callbacks. However, since these are examples and
not having a name for that argument confuses beginners, we decided to
have it present.
echobot.py¶
This is probably the base for most of the bots made with
python-telegram-bot
. It simply replies to each text message with a
message that contains the same text.
timerbot.py¶
This bot uses the
telegram.ext.JobQueue
class to send timed messages. The user sets a timer by using /set
command with a specific time, for example /set 30
. The bot then sets
up a job to send a message to that user after 30 seconds. The user can
also cancel the timer by sending /unset
. To learn more about the
JobQueue
, read this wiki article.
Note: To use JobQueue
, you must install PTB via pip install "python-telegram-bot[job-queue]"
conversationbot.py¶
A common task for a bot is to ask information from the user. In v5.0 of
this library, we introduced the
telegram.ext.ConversationHandler
for that exact purpose. This example uses it to retrieve
user-information in a conversation-like style. To get a better
understanding, take a look at the state diagram.
conversationbot2.py¶
A more complex example of a bot that uses the ConversationHandler
.
It is also more confusing. Good thing there is a fancy state diagram.
for this one, too!
nestedconversationbot.py¶
A even more complex example of a bot that uses the nested
ConversationHandler
s. While it’s certainly not that complex that
you couldn’t built it without nested ConversationHanldler
s, it
gives a good impression on how to work with them. Of course, there is a
fancy state diagram
for this example, too!
persistentconversationbot.py¶
A basic example of a bot store conversation state and user_data over multiple restarts.
inlinekeyboard.py¶
This example sheds some light on inline keyboards, callback queries and message editing. A wiki site explaining this examples lives here.
inlinekeyboard2.py¶
A more complex example about inline keyboards, callback queries and message editing. This example showcases how an interactive menu could be build using inline keyboards.
deeplinking.py¶
A basic example on how to use deeplinking with inline keyboards.
inlinebot.py¶
A basic example of an inline bot. Don’t forget to enable inline mode with @BotFather.
pollbot.py¶
This example sheds some light on polls, poll answers and the corresponding handlers.
passportbot.py¶
A basic example of a bot that can accept passports. Use in combination
with the HTML page.
Don’t forget to enable and configure payments with
@BotFather. Check out this
guide
on Telegram passports in PTB.
Note: To use Telegram Passport, you must install PTB via pip install "python-telegram-bot[passport]"
paymentbot.py¶
A basic example of a bot that can accept payments. Don’t forget to enable and configure payments with @BotFather.
errorhandlerbot.py¶
A basic example on how to set up a custom error handler.
chatmemberbot.py¶
A basic example on how (my_)chat_member
updates can be used.
webappbot.py¶
A basic example of how Telegram WebApps can be used. Use in combination with the HTML page. For your convenience, this file is hosted by the PTB team such that you don’t need to host it yourself. Uses the iro.js JavaScript library to showcase a user interface that is hard to achieve with native Telegram functionality.
contexttypesbot.py¶
This example showcases how telegram.ext.ContextTypes
can be used to
customize the context
argument of handler and job callbacks.
customwebhookbot.py¶
This example showcases how a custom webhook setup can be used in
combination with telegram.ext.Application
.
arbitrarycallbackdatabot.py¶
This example showcases how PTBs “arbitrary callback data” feature can be
used.
Note: To use arbitrary callback data, you must install PTB via pip install "python-telegram-bot[callback-data]"
Pure API¶
The rawapibot.py example example uses only the pure, “bare-metal” API wrapper.
