Stack Overflow doesn't provide language-specific implementations, it only offers the API as it is: a collection of endpoints for HTTP calls. Luckily, we have volunteers who write libraries and post them on Stack Apps, the dedicated Stack Exchange for API support. Here is a list of the most popular Python libraries; it includes Py-StackExchange which you've already found.
Support for those libraries is usually available by posting an answer to the 'question' announcing the library; in that respect, Stack Apps works a little counter-intuitively when compared to most Stack Exchange sites (though Meta and its announcements follow the same pattern). In this particular case, you can also drop an email to the maintainer.
