IDLEX Extension - A Promising IDE For Python.

[snippsat]

not a single one combines all of the requirements at one place.

I use different tools that i am happy with,not so concerned that one tools shall do it all.
Example VS Code can run Jupyter Notebooks inside Editor,but JupyterLab dos it better as that was is made for.

Can mention what i use VS Code tutorial main editor all OS,PyScripter(for fast stuff can run code no need to save,good REPL).
cmder as shell Windows,fish or default Linux.
ptpython REPL in shell,review.
JupyterLab for Notebboks eg pandas,plot ect.
