How to implement the singleton pattern in Python?
Article Introduction:There are three main ways to implement Singleton mode in Python: 1. Use a decorator to control the creation and reuse of class instances by defining closure functions. The advantages are that the code is clear and reusable, but the debugging is not intuitive enough; 2. Rewrite the \_\_new\_\_ method to maintain the instances within the class. The advantages are more native and object-oriented, but pay attention to multi-threaded safety issues; 3. Use the natural singleton characteristics of the module to directly create instances in the module and export and use them, which is simple and easy to maintain but poor flexibility. Choose the appropriate method according to actual needs: flexibly control the selection of decorators, object-oriented selection of \_\_new\_\_, and use the modules simply globally.

python singleton pattern example
Article Introduction:Use the __new__ method to control the class to create only one instance, but it should be noted that __init__ will still be executed repeatedly; 2. The decorator method is flexible and can be reused for multiple classes, without invading the internal structure of the class; 3. Module-level variables are the most recommended singleton implementation in Python, which is naturally thread-safe and concise; 4. In a multi-threaded environment, thread-safe and double check can be ensured; it is recommended to give priority to the use of module-level singletons, because they are simple, clear and easy to test, and other methods are only selected when complex control is needed.

What are some best practices for writing maintainable and scalable Python code?
Article Introduction:To make Python code easy to maintain and adapt to future changes, the key is to have clear structure, simple logic and follow common specifications. First, we must make clear responsibilities, modular design, split different functions into independent functions or classes, each function only does one thing, each class is only responsible for one type of behavior; second, we must control the length of the function to be within 20 lines, avoid excessive nesting, reduce coupling between classes, and give priority to combination rather than inheritance; third, we must have clear names, use nouns (such as user_list), function names start with verbs (such as save_user_to_db()), class names use big camels (such as DataProcessor), avoid abbreviations to improve readability; fourth, we must use type prompts and document strings reasonably, and add detailed do for each function
