Python's async/await: Concurrent, Not Parallel
async/await lets a single Python thread juggle multiple tasks, pausing one to work on another while it waits for I/O. It's ideal for network requests or database queries. The footgun: it won't speed up CPU-bound tasks, it only helps with waiting.
Python's async/await enables concurrency on a single thread, like a chef starting a slow-cooking dish and then chopping vegetables instead of just staring at the oven. It's perfect for I/O-bound work like high-performance web servers, database connection libraries, and distributed task queues where programs spend most of their time waiting. The biggest footgun is using it for CPU-bound work; it adds overhead and won't make heavy computation any faster.
