Can't import name "Dispatcher" from telegram

I am a beginner with python-telegram-bot, I have installed version the latest version 20.2.

I installed a package "python-telegram bot" but I got an import error upon running the code

ImportError: cannot import name "Dispatcher" from telegram.ext

I delved into the python-telegram-bot package and discovered that there is no module called Dispatcher, but several online tutorials directly imported Dispatcher from telegram.ext.

In my attempt to build a bot using Telegram, I have tried several times, but I have still received a message that says it cannot import the name ‘Dispatcher’ from the extension telegram.ext.As far as I am concerned, this error should be solved as soon as possible and I would appreciate if you could help me with it.

    You seem to be using a version >=20.0 of python-telegram-bot but your code is written for version <=13.15. Please either upgrade your code to v20 by reading the release notes and the transition guide or install a version of PTB that is compatible with your code base.
    Please note that the PTB team does not provide support for versions older than v20 anymore.

    According to the latest documentation suggested by @CallMeStag, you need to do some tweaking to your code lol. There’s a lot of upgrade happening with the api. Here is a sample code i tried:

    import telegram
from telegram.ext import Updater, CommandHandler, MessageHandler, Application, ContextTypes

import requests
Token = 'My Token'

application = Application.builder().token(Token).build()



async def start(update: telegram.Update, context: ContextTypes.DEFAULT_TYPE):
    await context.bot.send_message(chat_id=update.effective_chat.id, text="I'm a bot, please talk to me!")


async def help(update: telegram.Update, context: ContextTypes.DEFAULT_TYPE):
    await context.bot.send_message(chat_id=update.effective_chat.id, text='''
    /start -> Welcome to tryTalk url shortener
    /help -> Send me a url you'll like to shorten and I'll reply back with a short version of your url
    /shorten -> Enter a url 
    /contact -> Contact the bot creator
    ''')


async def shorten(update: telegram.Update, context: ContextTypes.DEFAULT_TYPE):
    await context.bot.send_message(chat_id=update.effective_chat.id, text="Enter your URL")


async def contact(update: telegram.Update, context: ContextTypes.DEFAULT_TYPE):
    await context.bot.send_message(chat_id=update.effective_chat.id, text='''

    ''')




application.add_handler(CommandHandler('contact', contact))
application.add_handler(CommandHandler('help', help))
application.add_handler(CommandHandler('shorten', shorten))
application.add_handler(CommandHandler('start',start))

application.run_polling()
application.idle()
