HackerRank: Thoughts? Any other similar platforms?

I recently started doing some exercises on HackerRank but am struggling with python3 even though I like to believe that I am fairly comfortable with it (Since I have done several projects and Kaggle competitions with it). Is it just me then? I have a data science background and not a cs background but am trying to be better at coding. Are there any other websites out there like HackerRank that prepare you for coding interviews?

HR isn't going to teach you to be a better software engineer. It's going to teach you to be a better problem solver. The language you're using shouldn't matter that much as long as you are comfortable with it.

Maybe for your next problem you should write out a paragraph about how someone could get the solution with a pencil and paper.
