I HAVE REMATCHED THE CODE, IT IS CORRECT. PLEASE TELL ME WHAT IS THE MISTAKE.
MY CODE
Using logging module to log any warnings
import logging
from telegram.ext import Updater, CommandHandler, MessageHandler, Filters
Enable logging
logging.basicConfig(format=’%(asctime)s - %(name)s - %(levelname)s - %(message)s’,

By default, any function passed inside command handler will get 2 arguments which are bot and update
bot represents bot object and update represents the update which we have received
Any function which we define inside handler will take bot and update as arguments
def start(bot, update):
print(update)
author = update.message.from_user.first_name # Name of sender of the message
#msg = update.message.text # Actual message received from user
reply = “Hi! {}”.format(author) # Reply to be sent to the user
bot.send_message(chat_id=update.message.chat_id, text=reply) # Sending reply
def _help(bot, update): # To provide help to user
help_txt = “Hey! This is a help text.”
bot.send_message(chat_id=update.message.chat_id, text=help_txt)
def echo_text(bot, update): # Function to give response if a text message is received
reply = update.message.text # Since it is a echo bot, it will simply send the same message as reply which is received from user
bot.send_message(chat_id=update.message.chat_id, text=reply)
def echo_sticker(bot, update): # Function to give response if a sticker message is received
bot.send_sticker(chat_id=update.message.chat_id, sticker=update.message.sticker.file_id) # Since it is a echo bot, it will simply send the same message as reply which is received from user
def error(bot, update): # Error handler
logger.error(“Update ‘%s’ caused error ‘%s’”, update, update.error)
def main():
updater = Updater(TOKEN) # Updater object to receive updates from telegram server
dp = updater.dispatcher # It will handle the updates like giving response on received message
# For dispatcher, we need multiple handlers to handle different situations
dp.add_handler(CommandHandler("start", start)) # If user types /start, call start() function
dp.add_handler(CommandHandler("help", _help)) # To provide help
dp.add_handler(MessageHandler(Filters.text, echo_text)) # To handle messages. We have filters to determine what type of message have we received, like, if it is text then echo_text function should be called
dp.add_handler(MessageHandler(Filters.sticker, echo_sticker)) # To handle stickers
dp.add_error_handler(error) # For handling all kind of errors
updater.start_polling() # To start polling
logger.info("Started polling...")
updater.idle() # It will wait for you to press Ctrl+C to stop polling
In any telegram bot, if we put / before any query, it means it is a command
if name == “main”:
main()
