$ sudo apt-get install python3-dev libffi-dev libssl-dev

• RHEL/CentOS (for python 3.6):

$ sudo yum install python36u-devel openssl-devel
$ sudo yum group install "Development Tools"

• FreeBSD:

$ pkg install ca_root_nss

• Windows:

  • VS Build Tools

  • Windows Extension for Python

You can install pytgram using pip:

$ pip install pytgram

Usage

Webhook setup

from pytgram import set_webhook

set_webhook('bot_token', 'https://example.com')

If you use self-signed certificate - the pass path to it:

from pytgram import set_webhook

set_webhook('bot_token', 'https://example.com', 'path/to/cert.pem')

Creating a simple bot

import sys

from twisted.python import log
from twisted.internet import reactor, ssl
from twisted.internet.defer import inlineCallbacks

from pytgram import TelegramBot, MessageHandler, web_hook

bot = TelegramBot('bot_token')


@MessageHandler(content=['text'])
@inlineCallbacks
def text_handler(message):
    result = yield bot.send_message(chat_id=message.chat.id,
                                    text=message.text[::-1])
    print(result)


@MessageHandler(command=['start'])
@inlineCallbacks
def start_handler(message):
    result = yield bot.send_message(chat_id=message.chat.id,
                                    text='Received command "start"')
    print(result)


def main():
    log.startLogging(sys.stdout)
    ssl_context = ssl.DefaultOpenSSLContextFactory('ssl/secret.key',
                                                   'ssl/cert.pem')
    # If want use reverse proxy, then replace listenSSL on listenTCP.
    reactor.listenSSL(443, web_hook(bot.token), ssl_context)
    reactor.run()


if __name__ == '__main__':
    main()

If you want to use polling mode, you can do it like that:

import sys

from twisted.python import log
from twisted.web.server import Site
from twisted.web.resource import Resource
from twisted.internet import reactor
from twisted.internet.defer import inlineCallbacks

from pytgram import TelegramBot, MessageHandler, polling

bot = TelegramBot('bot_token')


@MessageHandler(content=['text'])
@inlineCallbacks
def text_handler(message):
    result = yield bot.send_message(chat_id=message.chat.id,
                                    text=message.text[::-1])
    print(result)


@MessageHandler(command=['start'])
@inlineCallbacks
def start_handler(message):
    result = yield bot.send_message(chat_id=message.chat.id,
                                    text='Received command "start"')
    print(result)


def main():
    log.startLogging(sys.stdout)
    reactor.listenTCP(8080,  Site(Resource()))
    polling(bot, interval=10)
    reactor.run()


if __name__ == '__main__':
    main()
