DataDiff (Python Data Structures)

DataDiff is a Python library (version 2.2.0) designed to provide human-readable diffs of common Python data structures, including lists, tuples, sets, and dictionaries. It recursively compares nested structures and offers special handling for multi-line strings, presenting them in a unified diff format. The library also provides drop-in replacements for some `nose` assertions, displaying clear data differences upon assertion failures. The project has a slower but consistent release cadence.
