By studying the "Old Boy Python Advanced Operation and Maintenance Advanced Video Tutorial", you can use Python to quickly generate the prototype of the program (sometimes even the final interface of the program), and then rewrite the parts with special requirements in a more suitable language. For example, the graphics rendering module in 3D games, which has particularly high performance requirements, can be rewritten in C/C++ and then encapsulated into an extended class library that can be called by Python. It should be noted that you may need to consider platform issues when using extended class libraries, and some may not provide cross-platform implementation.
