ADD PythonDataScienceHandbook For data-analyst

[Takenforgranted]

Python Data Science Handbook is a well-known book about Python data processing and analysis. Its original author has made the contents of this book and the corresponding notebook source code open source on GitHub. It is worth a look, especially for those who want to understand or urgently need Python's functions in data processing and analysis. Last year, I spent a few days reading this book online and browsing its jupyter notebook of source code notes. Before that, I had already taught myself the basic operations of python and libraries such as numpy and pandas at school, but my learning was rather fragmented. It was this book that helped me organize my thoughts. I don't know whether it is proper for this section,just some humble advice.
