      Preface

      Why Python?

      This textbook focuses on the Python programming language, but some readers might ask, “Why use Python instead of more established statistical packages such as IBM® SPSS® (Statistical Package for the Social Sciences) and SAS® (Statistical Analysis System) or other programming languages such as R?” Several advantages that Python has compared to SPSS and SAS are that Python is open source and can run on many platforms. Users are free to make copies, distribute, and even change the software. Like Python, the R programming language is also an open-source programming language used for data analytics. There is prolific use of both R and Python in the business world and for academic and research purposes. We focus on Python because we see a need for a text that presents Python programming specifically for those in the fields of social sciences and business to develop applications for data analytics. Whereas some may prefer R for statistical analysis and plotting charts, Python is a general-purpose scripting language used to develop applications with graphical user interfaces (GUIs), and many favor Python when working with text-based data. While there are possibilities of developing GUI applications using R, it is cumbersome to develop applications using R the way we approach them in this book. In our experience, covering the development of GUIs using the Python tkinter package (Chapter 11) right after control logic (Chapter 4) has piqued the interest of students through the creation of interactive, user-friendly applications. Although working with the Python tkinter package has some challenges, we have found that after successfully developing GUI-based applications, students are well prepared to work with other packages. Users of our textbook will become comfortable working with packages, and since there are over 200,000 Python packages available in the Python package repository, this is likely the most valuable takeaway from our textbook.

      Pedagogy

      Our book does not assume that the reader has any background in programming or statistics. This book has detailed code examples specified with line numbers to point out specific elements of Python as we cover them. Examples in each chapter focus on two large-scale data sets (Chicago Taxi Trips and the General Social Survey), building from the basics in the beginning chapters to the actual usage and analysis of the data sets in later chapters. These code examples are all available on a companion website at study.sagepub.com/researchmethods/statistics/kaefer-intro-to-python so that readers can execute the code examples to “learn by doing” as we introduce them in the material. We also include exercises in each chapter for readers to apply the concepts
