I upvoted Xiaoping Hu answer. Although for me PyCharm is a little bit overwhelming. I think that I will probably will go back to it, once I have firm python background. Now I am using Neovim + python terminal. :) I believe it is harder, but more rewarding in the long term. (Learning vim altogether with python). And for sure it does not slow down the machine. :D

I want to just add, that I am fairly ok in r language (I was often using Rstudio - I see PyCharm as its equivalent for Python), so I know my way around high level language.
