Python s standard library comes equipped with several built in packages for developers to begin reaping the benefits of the language instantly One such package is the multiprocessing module which enables the systems to run multiple processes simultaneously In other words developers can break applications into smaller threads that can run independently from their Python code Python Multiprocessing Tutorial DataCamp. Using Process The Process class in multiprocessing allocates all the tasks in the memory in one go Every task created using the Process class has to have a separate memory allocated Imagine a scenario wherein ten parallel processes are to be created where every process has to be a separate system process Python multiprocessing Process class is an abstraction that sets up another Python process provides it to run code and a way for the parent application to control execution There are two important functions that belongs to the Process class start and join function At first we need to write a function that will be run by the process
