Hi @maahijoshi28 ,
First, you need to create a Telegram bot using BotFather, as mentioned in the video. A HTTP API token will be generated for your bot. You need to paste this token in line 10 of your code, where it is mentioned to replace it with your actual bot token. After that, type /start
in your Telegram bot to activate it, and then run your code.
Please try this and let us know if you have any doubts.
