Mastering Metaprogramming in Python: Control Everything You Want
Metaprogramming techniques such as metaclasses are somewhat obscure and difficult to comprehend for most people, and most of the time, we don't need to use them. However, the implementation of most frameworks utilizes these techniques so that the code written by users can be concise and easy to understand. If you want to gain a deeper understanding of these techniques, you can refer to some books such as *Fluent Python* and *Python Cookbook* (some content of this article is referenced from them), or read some chapters in the official documentation, such as the descriptor How - To mentioned above, and the Data Model section, etc. Or directly examine the Python source code, including the source code written in Python and the CPython source code.

Why Python’s Sort Is Faster Than You Think
Timsort is a sorting algorithm that combines merge sort and insertion sort, and it has good efficiency in practice. Tim Peters designed this algorithm in 2002 and it is used in Python (TimSort is the default implementation of list.sort in Python). The algorithm finds sorted blocks - partitions in the data, where each partition is called a run, and then merges these runs according to certain rules. Python has been using the Timsort algorithm for sorting since version 2.3. Now, Java SE7 and Android also use the Timsort algorithm to sort arrays.

Go's http.ServeMux Is All You Need
"Which router library should I choose?" has always been a common question faced by Go beginners. After the release of Go 1.22, the answer to this question may change. Many developers will find that the new standard library mux is sufficient to meet their needs, eliminating the need to rely on third - party packages. Of course, some developers will continue to choose the familiar third - party libraries, which is also reasonable. Routers like gorilla/mux still have more functions than the standard library. In addition, many Go programmers will choose lightweight frameworks like Gin because it not only provides a router but also additional tools required to build a web backend.
