Determining the current process

Working with processes is at times considerably difficult, and significant debugging is therefore required. One of the methods of debugging a multiprocessing program is to identify the processes that encounter errors. As a refresher, in the previous countdown example we passed a name parameter to the count_down() function to determine where each process is during the countdown.

This is, however, unnecessary as each Process object has a name parameter (with a default value) that can be changed. Naming processes is a better way to keep track of running processes than passing an identifier to the target function itself (as we did earlier), especially in applications with different types of processes running at ...
