Sun Lingdi: currently, limited public information is available, and details such as nationality, dates of birth and death, educational background, and specific professional positions have not been clearly recorded. According to the library holdings, Sun Lingdi has only one work, A Concise Course in Python Programming (Second Edition), which falls under the category of programming and design. Positioned as a "concise course," the book is intended for learners of the Python language, and its content is expected to focus on a systematic explanation of basic syntax and introductory programming design, helping readers build programming thinking and develop the ability to write code in practice through a tutorial format. The existence of a second edition also suggests that the textbook underwent revision and improvement through reader use. Because other information about the author is unavailable, a complete evaluation of the author's writing style and academic influence cannot yet be developed; readers may instead understand the author's teaching approach and organizational choices through the book's specific chapters and exercises.
