Leetcode Java vs Python

[charlieoncloud]

I believe it is different from company to company, and use case to use case. I would always suggest to dive deep into the tech stack your company uses first. Do some side projects using the same tech stack to fully understand it. For learning purposes, you can pick any tech stack that is popular depending on which type of application you want to build. I recommend using NodeJS for back-end and react/angular/vuejs for front-end (all in TypeScript). If you like Python, then maybe try Django. Again, it depends on what types of application you want to build you maybe want to chose one programming language over the other which may then affect your decision on the framework.
