Run coroutines and tasks in Python Naturally, the most common use for asyncio is to run the asynchronous parts of your Python script. This means learning to work with coroutines and tasks.

For example, using an index of -1 is a handy way to grab the last item from a list no matter the size of the list. In that case, list_of_ints[-1] yields 3, and list_of_objects[-1] yields None.
