clean code that allows developers to write style code that fits the shell script. Python is an interpretive language, which means that there is no need to compile. This makes Python the ideal scripting language. Python also reads, interprets, and outputs a looping style that allows developers to quickly try new code through the interpreter. Developers can implement some of their ideas without having to rewrite the entire program. Python is a fu

The simplest way to implement MVC in PHP-someone in the model Group said yesterday that using MVC allowed the program to perform a lot of database operations, reducing the performance, which surprised me. MVC is just a framework and has nothing to do with database operations. MVC only provides a clear programming and development mode. as long as you handle well, you cannot perform many unnecessary database operations. If an MVC allows a programmer to
