Well, no, why would you assume that? I started to use Linux - in VMs -
because I had to make sure that my cross-platform java/jython Tomcat
program would work right on Linux. Why, for example, would I think to
install Idle from the package manager when it, or things like that, were
always in my experience installed with pip? For that matter, "sudo
apt-get install pip" won't install pip. You need to use a different
name, and it may or may not be different for different distros.

No, I came to use Linux they way I said, but I didn't find those things
to be obvious. That's why I've started mentioning them on this list
when it seems like they might be useful.

Furthermore, people have been having trouble getting certain PyQt
programs working on Ubuntu 22.04 (and 20.xx before it) (yes, I know, not
what the OP asked about). The solution is pretty non-obvious and
requires a particular .so library file to be installed, if you can
discover which one and how to do that. I mention this in support of
what I said about a Windows Python user being likely to find things
harder, not easier, on Linux.

And please, let's not start a flame war about this! I'm passing on what
I've experienced, that's all. Yes, I know that there are some Python
packages that need to be built and that usually works better on Linux.
And I'll agree that some Python programs are snappier to load and run on
Linux than on the same machine running Windows, even in a Linux VM guest.
