What is Bot?

\n

According to Wikipedia, It is a software application that runs automated tasks (scripts) over the Internet. In other terms, It is a program written to mimic human behaviour in order to perform some tasks. Bots take input and do simple and repetitive tasks, which is much faster than humans.

\n

There are two types of bots:

\n\n

In this, We will make Telegram Chatbot, which would send a copy of the input that the user has sent.

\n

Making our Telegram Chatbot

\n

We will be using Python language to make the bot and will be using Telegram package for our bot.\nYou can know more about the telegram package from here

\n

Firstly, we will generate our telegram token. Below are the steps to follow to generate your own token.

\n
    \n
  1. Search BotFather on Telegram.
    2. \n
  2. Type /start to get started.
    3. \n
  3. Type /newbot to get a bot.
    4. \n
  4. Enter your Bot name and unique Username, which should end with the bot.
    5. \n
  5. Then, you would get your Bot token.
    6. \n
\n

After generating our token, we will make a python program to create a Telegram bot that will send the Text, Emojis, and Stickers similar to the user's input.

\n\n
import logging\nfrom telegram.ext import Updater, Filters, CommandHandler, MessageHandler
\n
logging.basicConfig(format='%(asctime)s - %(name)s - %(levelname)s - %(message)s',     #take time,level,name\n                    level=logging.INFO)\nlogger = logging.getLogger(__name__)
\n

This script does a basic configuration for the logging system. It takes time, level, and name.

\n\n
TOKEN = "ENTER YOUR TOKEN"
\n\n
def start(bot,update):\n    name  = update.message.from_user.first_name  #first name of the user messaging\n    reply = "Hi!! {}".format(name)\n    bot.send_message(chat_id = update.message.chat_id, text = reply)      #sending message\n\ndef help(bot,update):\n    reply = "How can I help You"\n    bot.send_message(chat_id = update.message.chat_id, text = reply)  #sending message\n\ndef echo_text(bot,update):\n    reply = update.message.text\n    bot.send_message(chat_id = update.message.chat_id, text = reply)\n\ndef sticker(bot,update):\n    reply = update.message.sticker.file_id\n    bot.send_sticker(chat_id = update.message.chat_id, sticker = reply)\n\ndef error(bot,update):\n    logger.error("Shit!! Update {} caused error {}".format(update,update.error))
\n

start function would be taking the user's input and would be sending, Hi, with the user's name.

\n

help function will prompt the message of how can I help you.

\n

echo_text and sticker function will send the same message or the stickers which the user has sent.

\n

error function would be printing the error message on the command prompt.

\n\n
def main():\n    updater = Updater(TOKEN)  #take the updates\n    dp = updater.dispatcher   #handle the updates\n\n    dp.add_handler(CommandHandler("start", start))\n    dp.add_handler(CommandHandler("help", help))\n    dp.add_handler(MessageHandler(Filters.text, echo_text))   #if the user sends text\n    dp.add_handler(MessageHandler(Filters.sticker, sticker))  #if the user sends sticker\n    dp.add_error_handler(error)\n    updater.start_polling()\n    logger.info("Started...")\n    updater.idle()\n\nif __name__=="__main__":\n    main()
\n
\n

Save the program and execute it to check the working of the telegram bot on telegram.

You can get the source code to make the Telegram bot from this Github Repository Bot :robot:. You can also make some changes to the code to make the bot do cool stuff such as Getting News, Articles, or Movies recommendations.
