The team aims at covering 100% of all of Python that makes sense in a browser environment

The documentation maintains a list of Python features that are not supported yet. For most of them, it's just a question of time and work by the development team

The only thing that is difficult to implement correctly is generators, since only few Javascript engines support "yield". Brython implementation is not perfect, but for the moment it doesn't break any of the modules in the standard distribution that have been included
