Tasks overview. Tasks are functions: they can take inputs, perform work, and return an output. A Prefect task can do almost anything a Python function can do. Tasks are special because they receive metadata about upstream dependencies and the state of those dependencies before they run, even if they don't receive any explicit data inputs from them.

When a function becomes a flow, its behavior changes, giving it the following advantages: All runs of the flow have persistent state.
