Which interpreter on my computer should I use?

[magic]

I am using visual studio code and there is a menu where I can pick interpreter like below.



There are so many of them. I feel like I need to clean them up somehow.
Is there a way to do it?

Out of these 9 interpreters, which one to use?
And why does it say (venv) in Python 3.6.5::Anaconda, Inc.?
What's the difference between the one with venv and all the others?

Look at VS Code from start

No do not try to clean up if you don't know what you do.
Virtual environment can be cleaned up,but do not mess with OS install of Python.

Out of these 9 interpreters, which one to use?

The one you want to work with
You have Python 3.7,so use that.
Test with python3 and pip3 -V command line and see if it point to 3.7.

And why does it say (venv) in Python 3.6.5::Anaconda, Inc.?

Because it's made a virtual environment with Anaconda.
Look at my tutorial here to learn more about Anaconda.
