Echo Bot using Python Telegram Bot
#!/usr/bin/env python # -*- coding: utf-8 -*- # This program is dedicated to the public domain under the CC0 license. """ Simple Bot to reply to Telegram messages. First, a few handler functions are defined. Then, those functions are passed to the Dispatcher and registered at their respective places. Then, the bot is started and runs until we press Ctrl-C on the command line. Usage: Basic Echobot example, repeats messages. Press Ctrl-C on the command line or send a signal to the process to stop the bot.
