A few words for the second edition

For the second edition, we have reorganized the structure of the book by adding more chapters related to finance. This is recognition and response to the feedbacks from numerous readers. For the second edition, the first two chapters are exclusively devoted to Python. After that, all remaining chapters are associated with finance. Again, Python in this book is used as a tool to help readers learn and understand financial theories better. To meet the demand of using all types of data by various quantitative programs, business analytics programs and financial engineering programs, we add Chapter 4, Sources of Data. Because of this restructuring, this edition is more suitable for a one-semester course such as Quantitative Finance, Financial Analysis using Python and Business Analytics. Two finance professors, Premal P. Vora, at Penn State University, Sheng Xiao, at Westminister College, have adopted the first edition as their textbook. Hopefully, more finance, accounting professors would find the second edition is more suitable for their students, especially for those students from a financial engineering program, business analytics and other quantitative areas.
