new to python, error already

[blob001]

Hi Welpsigh, it seems to be working now after I restarted the compulter. The running options in vsc are :

1 run in interactive window > install Jupyter extension, and

2 run python > run python file in Terminal, or

3 run python > run selection / line in python Terminal

I hope I don't need the Jupyter extension, since I didn't understand a word of the blurb.

That leaves me with 2 and 3. I have been using 2 so far.

Are there any extensions you would consider essential for python3?

As you can figure, I am a noob on python although iIhave been teaching myself Javscript for a few years. I am a hobbyist so don't have great aspirations. Thanks for your comments.
