Python Multi-process

1, Multi-threaded understanding

A thread is the smallest execution unit, and a process consists of at least one thread. Threads are characterized by the ability to share memory and variables between threads, with less resource consumption. How to schedule processes and threads is entirely up to the operating system, and the program itself cannot decide when to execute and how long it takes to execute.
