Quote:Is Jupyter Notebook still being used?Absolutly. Be aware that there is now a great 'studio' called Jupyter Lab. Notebook can be run directly from Jupyter Lab.
Quote:Do I need to update to current Python version on my computer?The latest version of Python is 3.11.5.
I would recommend updating to 3.11.5, or at least 3.11.4
There are so many new additions, you would struggle with 3.9.6. Everything still works, packages created with newer versions may have difficulties.
You can review the release notes from the various releases here
I would also highly recommend using virtual environments.
I have used pyenv for several years, and love it. See Snippsat's page on this here
