By: Ashish Kumar

Overview of this book

pandas is a popular Python library used by data scientists and analysts worldwide to manipulate and analyze their data. This book presents useful data manipulation techniques in pandas to perform complex data analysis in various domains. An update to our highly successful previous edition with new features, examples, updated code, and more, this book is an in-depth guide to get the most out of pandas for data analysis. Designed for both intermediate users as well as seasoned practitioners, you will learn advanced data manipulation techniques, such as multi-indexing, modifying data structures, and sampling your data, which allow for powerful analysis and help you gain accurate insights from it. With the help of this book, you will apply pandas to different domains, such as Bayesian statistics, predictive analytics, and time series analysis using an example-based approach. And not just that; you will also learn how to prepare powerful, interactive business reports in pandas using the Jupyter notebook. By the end of this book, you will learn how to perform efficient data analysis using pandas on complex data, and become an expert data analyst or data scientist in the process.

Understanding the pandas file hierarchy

Generally, upon installation, pandas is installed as a Python module in a standard location for third-party Python modules. In the following table, you will see the standard installation location for Unix/ macOS and the Windows platform:

Platform

Standard installation location

Example

Unix/macOS

prefix/lib/pythonX.Y/site-packages

/usr/local/lib/python2.7/site-packages

Windows

prefix\Lib\site-packages

C:\Python27\Lib\site-packages

If Python installation was done with Anaconda, then the pandas module can be found in the Anaconda directory, within a similar file path: Anaconda3\pkgs\pandas-0.23.4-py37h830ac7b_0\Lib\site-packages\pandas.

Now that we have had a look at the module on third-party Python modules, we will understand the file hierarchy. There are eight types of file in the installed Pandas library....
