Pyth3: Python Text Markup and Conversion

Pyth3 (version 0.7) is an incomplete and unmaintained port of the Python 2 `pyth` library, intended for text markup and conversion between formats like RTF and XHTML. The project explicitly states that while some components were partially upgraded for Python 3, many parts, including tests, are known to be broken, and the library is primarily targeted at Python 2.7. The last release was in February 2019, indicating it is no longer actively developed.
