I understand that it is the same Python version directly after a new system installation. But what happens when the user later change/update his Pyhon? Think about the "worst case" when the user replaces our Pyhon with whatever self-compiled Pyhon. Are byte-compiled Python .pyc and .pyo files the same for any Python and/or is any Python sufficiently smart to know when .pyc and/or .pyo files are outdated (even if the matching .py files are unchanged)? > i would even recommend packaging > them so they get removed if you uninstall the package. Removal when uninstalling could also be done by whatever other magic (e.g. via %ghost or a %preun scriptlet in RPM). I wonder why in this case small RPMs seem not to count. For example the installed .pyc and .pyo files in python on a openSUSE 10.3 i386 system are more than 7MB and still about 1.6MB after "bzip2" so that those files should make the python RPM about 1.6MB bigger. At least according to http://www.python.org/doc/1.5.1p1/tut/node43.html I wonder if there is a noticeable advantage to provide .pyc and .pyo files in the RPM because it reads: "A program doesn't run any faster when it is read from a ".pyc" or ".pyo" file than when it is read from a ".py" file; the only thing that's faster about ".pyc" or ".pyo" files is the speed with which they are loaded." I am no Python expert at all and I would be happy if a Python expert could provide some background information.
