I have tried using Django but got lots of error in this block of code that I have taken from GitHub will take user input and then try to understand and then shows relent answer to us through the text file that I have provided

Answer 1

if you want every thing run in client side I think you should use pyscript otherwise you must execute all your python code in server side program like django and send result to client with proper html/css/js libraries
