please help me to sort this problem iam using pycharam

Answer 1

You need to import it separately in your project. To do that you can refer below link: https://www.jetbrains.com/pycharm/guide/tips/install-and-import/

Also update your pycharm to its newest version of 2020.1.5 from the menu option go to Help -> Check for updates -> option will pop-up at right hand side below to update it
