"Firstly, there are three main Python concurrency APIs, they are:" asyncio, threading, multiprocessing, ... oh, and concurrent.futures

All kidding aside, I used the multiprocessing module lately and it was a mess. Do I want 'map', 'starmap', 'imap', etc.? All I wanted was to run a function multiple times with different inputs (and multiple inputs per function call) and to fail when any launched process failed rather than waiting for every input variation to execute and then telling me about the error(which honestly I didn't think was asking for too much).

There's a lot of functionality in the multiprocessing library and it has its own problems, but I wouldn't call it a "mess" from your description. map, starmap, and imap are all useful for different applications depending on your usage and priorities. I'll agree that it can sometimes be difficult to understand the differences and which is best for your use case, but having used in different use cases I certainly appreciate the different functions available.
