Python-for-Data-Analysiz

说明：  The scientific Python ecosystem of open source libraries has grown substantially over the last 10 years. By late 2011, I had long felt that the lack of centralized learning resources for data analysis and statistical applications was a stumbling block for new Python programmers engaged in such work. Key projects for data analysis (especially NumPy, IPython, matplotlib, and pandas) had also matured enough that a book written about them would likely not go out-of-date very quickly. Thus, I mustered the nerve to embark on this writing project. This is the book that I wish existed when I started using Python for data analysis in 2007. I hope you find it useful and are able to apply these tools productively in your work.
