With the help of this book, Python programmers can effectively solve a broad set of data analysis problems. I would like readers of this edition to find that the content is still almost as relevant in 2020 or 2021 as it is in 2017. We understand your time is important. We learn data manipulations such as aggregating, concatenating, appending, cleaning, and handling missing values, with NumPy and Pandas. Frustrated by cumbersome data analysis tools, he learned Python and started building what would later become the pandas project. He is a firm believer in agile practices and automated testing.

Wes is the main author of pandas, the popular open sourcePython library for data analysis. This structured approach enables you to select the pathway which best suits your knowledge level, learning style and task objectives. We learn data manipulations such as aggregating, concatenating, appending, cleaning, and handling missing values, with NumPy and Pandas.
