I encourage you to with MERN stack. MERN stack is mainly based on javascript so, you should master javascript. You can use JS for frontend (React,vue,angular) as well as backend (Node.js) and that's all you need to be a full stack developer. And its not compulsory to learn Python and Django with SQL. However SQL database you should know as a developer. But if you want to learn python its fine you can its easy to learn and a beautiful language and for python framework you can start with Flask to see how to feel working with python to build web applications. :)

I suggest you to go with JavaScript. From my perspective JavaScript is the language you should invest your time in. The community of javascript and lots of framework helps developer to build what they want to build in no time whether it a desktop, web, mobile based application or even you can use javascript as a backend as well. There are lot of frameworks you can start learning i suggest you to go with (react,vue) library both are easy to learn than angular which is a complete framework.

And if you want to go with python as a secondary tool then i suggest you to learn a python framework (Flask,Django).

I suggest you to go with MERN Stack (Mongo,express,react,Node). As you know python and django which is a plus point because you can use python and node as your backend and for front-end use react(easy to learn) and database of your choice.(Mongo or SQL)

Pycharm is all you need to get start coding in python or any of its framework. Its an awesome tool you should give it a try :)
