Not yet. In a previous article, Hal wrote:

I don't think this is actually correct. My experience building Viper is
the 'hardest' part is implementing the libraries. Not that it is 'hard'
per se, just quite laborious, and requiring continual fiddles to the
overall architecture, while juggling compromises between CPython
implementation details, and the needs of real CPython programs.
I consider the following modules basic: _builtins_, string, exception,
marshal, pickle, sys, os, posix, re, array, traceback, time (and a few
Interestingly, string, exception, and types work as written in pure
without modification (but 'string' is way too slow).
In addition, Viper will support a full scale, _builtin_ GUI, rational
numbers, and probably matrices.
I'd guess and Oberon version of Python would face the same issues:
I don't think that the 'python language' is much use without the
libraries people need to do actual work.
