There are common errors experienced by beginners when getting started with asyncio in Python.
They are:
- Trying to run coroutines by calling them.
- Not letting coroutines run in the event loop.
- Using the asyncio low-level API.
- Exiting the main coroutine too early.
- Assuming race conditions and deadlocks are impossible.

Half of the time taken to start an interpreter is taken up running “site import”. This is a special module called site.py that lives within the Python installation. Interpreters have their own caches, their own builtins, they are effectively mini-Python processes. Starting a thread or a coroutine is so fast because it doesn’t have to do any of that work (it shares that state with the owning interpreter), but it’s bound by the lock and isn’t parallel.
