Introduce new book
Live Python Design Patterns is the author’s latest book, keep your eyes open!
The book uses Python’s standard GUI toolkit, Tkinter, to illustrate each of the 23 design patterns with executable examples. On the one hand, readers can understand the application scenarios and problems of each design pattern in real software development work. On the other hand, by explaining the process of solving these problems, readers can understand how to judge the advantages and disadvantages of using design patterns when writing code, and make reasonable use of design patterns.
Readers who are interested in design patterns and want to learn and use them can quickly cross the threshold from understanding to using them. Readers wishing to learn Python GUI programming can use the examples in this book as a design and development reference; Readers who use Python for image analysis and data processing can quickly build their own systems based on the examples in this book.
