IDLE vs PyCharm as editors?

[snippsat]

I read somewhere that IDLE or Pycharm is the way to go for the program-to-app advantage.

IDLE is not the way to go,it's just bad think most agree about this.
Thonny is IDLE done right,if want an alternative.
Pycharm is a very strong editor for Python.

I VS Code(my quick review) which is a multi-language like Atom and Sublime text.
VS Code has very good Python support,as Microsoft has hired the creator of the Python extension.

A good REPL can also be important.
ptpython(review) or ipython.
