How to get current CPU and RAM usage in Python?

What"s your preferred way of getting current system status (current CPU, RAM, free disk space, etc.) in Python? Bonus points for *nix and Windows platforms.

There seems to be a few possible ways of extracting that from my search:

Using a library such as PSI (that currently seems not actively developed and not supported on multiple platform) or something like pystatgrab (again no activity since 2007 it seems and no support for Windows).
Using platform specific code such as using a os.popen("ps") or similar for the *nix systems and MEMORYSTATUS in ctypes.windll.kernel32 (see this recipe on ActiveState) for the Windows platform. One could put a Python class together with all those code snippets.

It"s not that those methods are bad but is there already a well-supported, multi-platform way of doing the same thing?

Simply put and clear. Thank you for sharing. How to get current CPU and RAM usage in Python? and other issues with ctypes Python module was always my weak point 😁. Will get back tomorrow with feedback

dis Python module is always a bit confusing 😭 How to get current CPU and RAM usage in Python? is not the only problem I encountered. I am just not quite sure it is the best method
