Via PyPI, OpenPGP in Python is just that. The author is also learning about Python as he goes:
This is an attempt at implementing OpenPGP in Python. This is also my first attempt at doing anything real in Python so [insert disclaimers and cries for help here]. I’m classifying this as “Pre-Alpha” since major changes are still pretty frequent. For testing in the meantime, an API and fairly usable command line application are included.
PyOpenPGP requires PyCrypto. Don’t let the humble author fool you, check out the demo.
