# Function Tasks

The tasks in this module can be used to represent arbitrary functions.

In general, users will not instantiate these tasks by hand; they will automatically be applied when users apply the @task decorator.

# FunctionTask



(fn, name=None, **kwargs)[source]

A convenience Task for functionally creating Task instances with arbitrary callable run methods.


  • fn (callable): the function to be the task's run method
  • name (str, optional): the name of this task
  • **kwargs: keyword arguments that will be passed to the Task constructor
  • ValueError: if the provided function violates signature requirements for Task run methods

task = FunctionTask(lambda x: x - 42, name="Subtract 42")

with Flow("My Flow") as f:
    result = task(42)
