Do python threads run in parallel

Web2 days ago · Threads are a means of concurrently performing different activities, and parallel computation is just one of several reasons why you might want concurrency. One use-case for threads in Python would be a multi-client network service in which a different thread serves each different client. Those threads can all concurrently wait for their ... As you can see, the previous format was executing the blocking function in the main thread, preventing you from being able to parallelize (e.g. it would have to finish that function execution before getting to the line where it calls the second function). The proper way to set the thread in a non-blocking fashion would be:
