Python is an ideal choice for accessing, manipulating, and gaining insights from data of all kinds. Python for Data Science introduces you to the Pythonic world of data analysis with a learn-by-doing approach rooted in practical examples and hands-on activities. You’ll learn how to write Python code to obtain, transform, and analyze data, practicing state-of-the-art data processing techniques for use cases in business management, marketing, and decision support.

You will discover Python’s rich set of built-in data structures for basic operations, as well as its robust ecosystem of open-source libraries for data science, including NumPy, pandas, scikit-learn, matplotlib, and more. Examples show how to load data in various formats, how to streamline, group, and aggregate data sets, and how to create charts, maps, and other visualizations. Later chapters go in-depth with demonstrations of real-world data applications, including using location data to power a taxi service, market basket analysis to identify items commonly purchased together, and machine learning to predict stock prices.

Reviews

"A great introduction to Python for data science in a compact package. I'm impressed with what Yuli Vasiliev included: the basics of Python, multiple angles at preparation, and a number of chapters on common types of data. The book is surprisingly visual for a field known for rows and columns—the location data was especially interesting to me. By the end of [Python for Data Science], I was ready to apply the principles to my own datasets."

"Python to help you evaluate information is a great skill to have. Python for Data Science, written by Yuli Vasiliev, is an excellent resource for someone interested in getting started with Data Science. Although not intended for beginners in data analytics or python programming, this book explains how to implement some essential python concepts, gives excellent code snippets for practice, and guides you on using a few important libraries useful for processing and analyzing data with code."
