Linux distros use an integrated package manager and are maintained by a cohesive community. What that means is that the SQLite package isn’t just used by Python, but by a bunch of other stuff as well. So all the maintainers of those packages have an interest in making sure that SQLite doesn’t break them. Whereas on Windows, the Python download has to include _all_ its dependencies, it cannot rely on a system-integrated package manager to automatically provide them. And the same is true for every other open-source package that anyone tries to pre-build for Windows. So they all have to provide their own installation routines, their own updates, their own testing ... in short, a lot of duplication of effort. This is expensive. -- http://mail.python.org/mailman/listinfo/python-list
