But it does not mean that multiprocessing is always better than multithreading. There are a lot of use cases where threads may be a better solution than processes. This is especially true for situations where low latency and/or high resource efficiency is required.

Still, it does not mean that you need to sacrifice all the useful abstractions from the multiprocessing module whenever you want to use threads instead of processes. There is the multiprocessing.dummy module that replicates the multiprocessing API, but uses multiple ...
