In Python we are mainly implemented through the thread and threading two modules, where Python's threading modules are packaged for thread and can be used more easily, So we use the threading module to implement multithreaded programming. Generally speaking, there are two modes of using threads, one is to create a function to execute the thread, pass it into the thread object, let it execute, the other is to inherit directly from thread, create a new
