Pandas is one of the most efficient scientific computing packages in Python. It has an enormous amount of power and flexibility to tackle any data task in a variety of ways. It is common for advanced users to write “ugly” Pandas code. With this book, you will explore data in Pandas through dozens of practice problems with detailed solutions in iPython notebooks
This book will provide you with clean, clear recipes and solutions on how to handle common data manipulation tasks. You will be introduced to Pandas and its various features. You will learn about working with different types of data sets, data manipulation, and data wrangling. You will explore the power of Pandas DataFrames and find out about Boolean and multi-indexing with Pandas.
