Python vs. Jython: A battle between performance, compatibility, and applications

Python is an interpreted language, and Jython is an implementation of Python that runs on the Java Virtual Machine (JVM). Interpreted languages generally execute slower than compiled languages because the interpreter needs to convert the code into machine instructions at run time. However, the JVM's just-in-time (JIT) compiler can compile Jython code into machine instructions, thereby increasing its execution speed. In terms of performance, Jython is generally slower than Python, but the speed difference is not huge. For simple scripts, Jython's performance may be comparable to Python. However, for complex tasks, Jython's overhead may become more noticeable. Compatibility Python has a large and mature library ecosystem, and

Python ORM Best Practices: Improving Code Efficiency and Maintainability

Object-relational mapping (ORM) is a programming technique used to map between object-oriented programming (OOP) languages and relational databases. In python, ORM framework allows developers to use Python objects to manipulate databases, thereby simplifying data management. By following best practices, you can improve the efficiency and maintainability of your PythonORM code. Best practice model design uses the single responsibility principle: dividing the responsibilities of the model into different classes makes the code clearer and easier to maintain. Avoid overloading: Try to avoid adding too many methods or attributes to the model class and keep the class simple. Use field type constraints: Use database field type constraints to validate and restrict model properties to ensure data integrity and consistency. Build relationships:

An in-depth guide to Python ORM: Master the basics of object-relational mapping

Object-relational mapping (ORM) is the middle layer that connects objects and relational databases. Using an ORM, you can use objects to manipulate the database, simplifying data processing and improving code readability. The foundation of ORM The core of ORM is to associate objects with tables, properties with columns, and methods with sql queries. When you save an object, the ORM converts it into a SQL query and sends it to the database. When you query an object, the ORM maps the database results back to the object.
