Uproot

Uproot is a Python library designed for reading and writing files in the ROOT format, commonly used in high-energy physics. It provides ROOT I/O functionality in pure Python and NumPy, without requiring the C++ ROOT installation. As part of the Scikit-HEP project, Uproot efficiently integrates with modern Python data analysis tools like NumPy and Awkward Array. The library is actively maintained, currently at version 5.7.3, with frequent updates and bug fixes.
