Basically, what that said is the global interpreter lock is something that allows only one thread at a time to be executed when you launch a python program in opposition of executing multiple threads at the same time (parallelism). when you launch a python program it create a process in memory. because of the GIL you cannot do parallelism in an efficient way, but if you are not using threads, you shouldn't care about. The GIL was relevant when we had one processor in our machine and honestly it facilitate the development of the core maintainers of the CPython. Now we have multicore processor, it start to be restrictive for some people, not all but some of them who need to compute data and want to use all the power they have.
Instead of giving you some examples I'll give you a link of some great presentations made by David Beazly Understanding the GIL: https://m.youtube.com/watch?v=Obt-vMVdM8s Embracing the GIL: https://m.youtube.com/watch?v=fwzPF2JLoeU Concurrency from the ground: https://m.youtube.com/watch?v=MCs5OvhV9S4 This guy will explain to you better than I I'll do. Hope that helps. Regards.
