Worked on the ferdymercury/root repository to enhance TH1 Python bindings, focusing on improving data analysis workflows for users. Developed in-place multiplication support using the *= operator on TH1 objects and enabled histogram filling with NumPy arrays, including optional weights for greater flexibility. Updated and published comprehensive documentation to describe these new user-facing features and clarified that pythonizations extend to all TH1 subclasses. The technical approach emphasized reducing Python-side boilerplate and increasing consistency across derived types. Utilized Python, NumPy, and documentation best practices to deliver these improvements, resulting in faster data processing and a more intuitive developer experience.
