What is concurrency?
Concurrency is working on multiple things at the same time. In Python, this can be done in several ways:
- With
threading, by letting multiple threads take turns. - By firing off a task and continuing to do other stuff, instead of waiting for an answer from the network or disk. This is how asynchronous IO operates with the
asynciolibrary. - With
multiprocessingwe’re using multiple processes. This way we can truly do more than one thing at a time using multiple processor cores. This is called parallelism.
