Pandas has rapidly become one of Python''s most popular data analysis libraries. With pandas you can efficiently sort, analyze, filter and munge almost any type of data. In   Pandas in Action, a friendly and example-rich introduction, author Boris Paskhaver shows you how to master this versatile tool and take the next steps in your data science career.

about the technology

Anyone who's used spreadsheet software will find pandas familiar. While its column-based grids might remind you of Excel or Google Sheets, pandas is more flexible and far more powerful. It can efficiently perform operations on millions of rows and be used in tandem with other Python libraries for statistics, machine learning, and more. And best of all, using pandas doesn't mean sacrificing user productivity or needing to write tons of complex code. It's clean, intuitive, and fast.
