Decorator Pattern in Python
Article Introduction：The decorator mode dynamically extends functions through functions or classes in Python without modifying its source code. 1. The essence of a decorator is to wrap functions or classes, such as adding logs, permission checking and other logic; 2. Use args and *kwargs to define decorators that support parameters; 3. Multiple decorators are executed in order from bottom to top; 4. Decorators with parameters are implemented through three-layer nesting; 5. Pay attention to using functools.wraps to retain meta information, and classes can also be used as decorators.

Understanding Python decorators syntax and usage
Article Introduction：Python decorators are essentially function wrappers, used to modify functions or class behaviors without changing the source code. 1. The decorator is a function that receives a function or class as an argument, and returns the wrapped version, for example, using the @decorator syntax is equivalent to func=decorator(func); 2. The wrapper function should use args and *kwargs to receive any parameters, and return the original function execution result to retain the return value; 3. The multi-layer decorator is executed in the order from bottom to top, that is, the decorator closest to the function is run first; 4. The class can also be used as a decorator, and the call method needs to be implemented, suitable for complex scenarios where state needs to be saved. After understanding these mechanisms, the decorator will become intuitive and practical.

How to troubleshoot memory leaks by process
Article Introduction：When encountering a memory leak problem, you must first confirm whether it is a memory leak, and then locate the specific program through process analysis. The steps include: 1. Use top or htop to view the continuously growing RSS; 2. Use ps to filter high memory occupancy processes and record PID; 3. Check suspicious memory mapped areas through pmap; 4. Use Valgrind, gperftools, perf or pprof to deeply analyze memory behavior; 5. If necessary, set memory limits, restart services regularly or enable swap as temporary measures. The entire process needs to start with phenomena, capture data and gradually narrow the scope with tools, and finally return to the code level to solve the problem.

HTML for Chat Application Interfaces
Article Introduction：When making a chat application interface, using HTML to build structure is a basic and critical step, which directly affects subsequent styles and interactions. First of all, the chat interface is generally divided into three parts: the top title bar, the message display area, and the input area. It is recommended to use a div to wrap the entire container and subdivate the area, with a clear structure for easy expansion. Secondly, each message is recommended to be wrapped with a div or li, including the sender, content, and time, and add incoming or outgoing classes according to the message type to distinguish styles. Third, the input area should include an input box and a send button, which supports carriage return sending and empty message judgment, and reserve space for automatically expanding the height. In addition, you need to pay attention to the message order, avoid too deep structure nesting, and use semantic tags reasonably to ensure that the HTML structure is simple and has
