Creating a Telegram bot using Python

3 min readNov 25, 2016

Considering that you already know what is a bot, I’ll try to explain how you can easily create a telegram bot in python. Here I will be usingpython-telegram-botlibrary for python (https://python-telegram-bot.org). It is a wrapper you can not refuse.

Obviously the first step is to have a Telegram account, if you do not have one, you can download the Telegram App for your device. Here I am using Telegram’s web interface (https://web.telegram.org/ ).

One cool thing about telegram is that, it comes up with its own bot BotFather ( I do not know if it is related to GodFather), where it helps you set up and manage your bots. Just say “hi” to that BotFather, it will show you a bunch of commands which can be used to control your bots.

Just a click or tap on /newbot will lead you to your first bot.

The moment you send “/newbot” to BotFather, it will guide you to create your own first bot. Further steps are easy to follow, so I’ll skip that part. Once you are done with naming your bot, you will receive a text containing token to use your bot. ( Keep this token confidential, if in any case, it is disclosed you can change the token any time. Do not worry BotFather is always at your service to guide you.)

So fire up your python console.

I use Python 3.5 and I recommend you to use the same as well. No offence to 2.7 users, the library I am using for creating the bot supports Python 2.7+.

python-telegram-bot — We have made you a wrapper you can’t refuse

This library is as cool as it’s tagline sounds. Don’t trust me ? Try it once.

Okay, as a part of this demonstration, I have used their own tutorial code which is in their github repo —https://github.com/python-telegram-bot/python-telegram-bot

To install the library : Open up your terminal / command prompt and run:

pip install python-telegram-bot

After installing the library, fire up your python console:

First, you have to create anUpdater object. Replace'TOKEN' with your Bot's API token.

>>> from telegram.ext import Updater
>>> updater = Updater(token='TOKEN')

For quicker access to theDispatcher used by yourUpdater, you can introduce it locally:

>>> dispatcher = updater.dispatcher

Now, you can define a function that should process a specific type of update:

>>> def start(bot, update):
...     bot.sendMessage(chat_id=update.message.chat_id, text="I'm a bot, please talk to me!")

The goal is to have this function called every time the Bot receives a Telegram message that contains the/start command. To accomplish that, you can use aCommandHandler (one of the providedHandler subclasses) and register it in the dispatcher:

>>> from telegram.ext import CommandHandler
>>> start_handler = CommandHandler('start', start)
>>> dispatcher.add_handler(start_handler)

And that’s all you need. To start the bot, run:

>>> updater.start_polling()

Give it a try! Start a chat with your bot and issue the/start command - if all went right, it will reply.

That’s all folks! You have your bot which says “I’m a bot, please talk to me!”. This might be an end to this story but this is not an end to the adventure you will begin. I urge you to read the documentations for this library and build your own bot.

All the codes here are copied from their first bot tutorial. Read more about this library here:
