"Recommended"

"The Scientific Computing and data analysis community has been waiting for this book for many years: a number of concrete practical recommendations, and a number of integrated application approaches. This book will certainly be a definitive guide to technical computing in the Python field over the next few years. ”

--fernando Pérez, University of California, Berkeley research scientist, founder of Ipython

"About the content"

Still looking for a complete course to control, process, organize, and analyze structured data with Python? This book contains a number of practical cases where you will learn how to efficiently address a wide range of data analysis issues using a variety of Python libraries, including NumPy, Pandas, Matplotlib, and Ipython.

Because author Wes McKinney is the main author of the Pandas Library, this book can also be used as a practical guide to scientific computing for data-intensive applications using Python. This book is suitable for analysts who have just contacted Python and Python programmers who have just come into contact with scientific computing.

Ipython this interactive shell as your primary development environment.

Learn the basics and advanced knowledge of numpy (numerical Python).

? Start with the data analysis tool from the Pandas library.

Use high-performance tools to load, clean, transform, merge, and reshape data.

? use Matplotlib to create scatter plots, as well as static or interactive visualization results.

Use Pandas's groupby function to slice, dice, and summarize datasets.

Handle a variety of time series data.

? Learn how to solve problems in web analytics, social sciences, finance, and the economy through detailed case studies.

about the author· · · · · ·

Wes McKinney, a senior data analysis expert, has deep research on various Python libraries (including NumPy, pandas, matplotlib, Ipython, etc.), and has accumulated rich experience in a great deal of practice. A large number of classic articles related to Python data analysis are being reproduced by various technology communities and are recognized as one of the authoritative figures in Python and the open source technology community. Developed the well-known open source Python library--pandas for data analysis, which has been widely praised by users. Prior to creating Lambda Foundry, a company dedicated to enterprise data analysis, he was a quantitative analyst at AQR Capital Management.
