Intervals

The `intervals` library (version 0.9.2) provides basic tools for handling intervals or ranges of comparable objects in Python. It supports defining closed, open, or half-open intervals and performing operations such as checking for containment. This specific package, maintained by kvesteri, appears to be abandoned, with no updates since 2016, and its functionality has largely been superseded by other, more actively maintained interval libraries like `portion` (which itself evolved from a library called `python-intervals`).
