If you are looking for something purely Python, then you can combine pyosmium for reading OSM data with SQLAlchemy for writing it into the database. This gives you maximum flexibility for the database schema. For an example on how to do it: https://github.com/waymarkedtrails/osgende/blob/master/tools/osgende-import This tool only imports the raw OSM data. If you want preprocessed geometries then you would need to have a look at pyosmiums shapely example. This is quite a bit slower than the Java and C++ importers mentioned in this thread but that would only be relevant if you do regular full planet imports. Regarding Windows compatibility: pyosmium does have a native library part. We do create pre-compiled versions for installation via pip but only for a handful of python versions and so far I had neither positive nor negative feedback if that actually works as intended.
