Description
> That said, knowing myself and my preference for getting things set up my way and keeping environments organized, I doubt @StuMakELL is convinced by simply being told to install Python. So, if anyone has suggestions for best practices when manually bundling Python and LLVM in an environment isolated from other installations, that maybe helpful.

> 2. Build lldb from source and set the `LLDB_PYTHON_RELATIVE_PATH` variable so resolve a custom Python install that's not in your PATH.

I don't understand why Python 3.11 is set as the default in Windows, especially when different versions of Python can create conflicts for libraries that rely on newer Python features. Could we provide a mechanism for users to manually specify the Python path?
Contributor guide
Research direction
Start by reviewing the Windows LLDB setup around liblldb.dll, python311.dll, and the LLDB_PYTHON_RELATIVE_PATH build variable. Compare the supported PATH-based workflow with the isolated-install cases described in the issue. Done means a documented or implemented mechanism lets users select a Python installation without relying on the default PATH setup.
