qresource files are intended to embed random data files into
single-executable style software distributions, to reduce the number of
moving parts. This is as opposed to doing proper installation management
unix style, and is of limited use on Windows too, as long as people ship
Qt itself as shared libraries necessitating a directory structure.

This is all fine and well for C++ programs where qresources get
statically linked into the executable itself, reducing the number of
files to be installed.

What's the point of it for generating *.py files with that data? You end
up with multiple files to distribute anyway.

pkg_resources.resource_filename() and its modern equivalent, the stdlib
importlib.resources, allows you to access real files through standard
pythonic mechanisms, without the wrapper abstractions and without an the
rcc compiler. There's no need to handle data blobs as python inline
strings, try to byte-compile something that doesn't really byte-compile
well, etc.

The resulting files are easily introspectable and modifiable in the
built software bundle (because they are the original files) and only get
read at the time of use.

Really -- what is the big attraction to using qresources in python?
