multiprocessing is a standard library module in Python that supports multiprocessing programming. It allows programs to execute in parallel across multiple processes, thereby fully utilizing the computational power of multi-core CPUs and improving program execution efficiency. Unlike threads (threading), processes are the basic units scheduled independently by the operating system, possessing their own memory space. … Read more
