The new Python client library of ServiceX, the novel data delivery system

Effective data extraction has been one of major challenges in physics analysis and will be more important in the High-Luminosity LHC era. ServiceX provides a novel data access and delivery by exploiting industry-driven software and recent high-energy physics software in the python ecosystem. In this talk, the newly designed client library will be extensively introduced with various practical examples. ServiceX in a physics analysis pipeline will be briefly discussed with an example. The future of ServiceX also will be briefly described.
