why does vscode execute my selection so slowly in python console?

Question

This has been annoying me for weeks, it's usually not this bad but it's honestly like a snail at this point.

I can either run a specific line, or select some code and run the selection which sends that selection to the python console.

Why does this happen so slowly? See the gif...

Any thoughts on how I could fix this?

Yes I used to use spyder but it had so many issues (i.e. freezing, crashing, code collapsing errors, matplotlib backend issues, etc.) that I jumped ship - quite happy with VSCode minus this.. — Derek Eden, May 22 '20 at 03:34
How much text are you sending to the terminal? That looks like a ton which could cause buffering issues. I would say that if you're sending more than 5 lines at a time you may want to look at a different workflow like using the interactive window. — Brett Cannon, May 25 '20 at 20:29
it's weird, sometimes I can send as many as I want and it runs almost instantly, sometimes it will happen like this with even 1 line — Derek Eden, May 26 '20 at 02:07

Two Solutions:

1) Well first one is that you can try by changing the default terminal Powershell to Command Prompt

Here are the two guide for you on how to change the terminal

2) Start VSCode with the --ignore-gpu-blacklist flag and see if it solve any performance issues
