An async application runs entirely in a single process and a single thread, which is nothing short of amazing. Of course this type of concurrency takes some discipline, since you can't have a task that holds on to the CPU for too long or else the remaining tasks starve. For async to w...
Python's Global Interpreter Lock or GIL, in simple words, is a mutex (or a lock) that allows only one thread to hold the control of the Python interpreter at any one time. In this article you'll learn how the GIL affects the performance of your Python pr
