pySiDR: Python Event Reconstruction for SiD

Event reconstruction in the ILC community has typically relied on algorithms implemented in C++, a fast compiled language. However, the Python package pyLCIO provides a full interface to tracker and calorimeter hits stored in LCIO files, opening up the possibility to implement reconstruction algorithms in a language uniquely well suited to working with large lists of hits built with list comprehensions. Python, an interpreted language which can perform complex tasks with minimal code, also allows seamless integration with powerful machine learning tools developed recently. We discuss pySiDR, a Python package for SiD event reconstruction.
