Multiprocessing Pool apply In Python
To use the multiprocessing pool map function with multiple arguments you will need to use the starmap method instead The starmap method is similar to map but it allows you to pass iterable arguments to the function using the operator Here s an example of how you might use starmap to apply a function to multiple pairs of How to use multiprocessing pool map with multiple arguments W3docs. Multiprocessing Pool map in Python The map function on the multiprocessing pool only takes a single argument If our target function takes more than one argument we can use the starmap function instead It takes an iterable of iterable where each nested iterable provides arguments for one call to the target task function For example The multiprocessing module in Python provides several APIs to create and manage multiple child processes In this article we will focus on how to use the pool map function with multiple arguments Introduction to pool map The pool map function in the multiprocessing module applies a function to each element of a given iterable in
