Operator Tasks

---

The tasks in this module can be used to represent builtin operations, including math, indexing, and logical comparisons.

In general, users will not instantiate these tasks by hand; they will automatically be applied when users apply inline Python operators to a task and another value.

GetItem

class

prefect.tasks.core.operators.GetItem

(default=<no default>, *args, **kwargs)[source]

Helper task that retrieves a specific index of an upstream task's result.

Args:

• default (Any): the object to use as the default
• *args (Any): positional arguments for the Task class
• **kwargs (Any): keyword arguments for the Task class

methods:
prefect.tasks.core.operators.GetItem.run (task_result, key, default=<no default>)[source]
Args: task_result (Any): a value key (Any): the index to retrieve as task_result[key] default (Any): the object to use as the default

---

GetAttr

class

prefect.tasks.core.operators.GetAttr

(default=<no default>, *args, **kwargs)[source]

Args:

• default (Any): the object to use as the default
• *args (Any): positional arguments for the Task class
• **kwargs (Any): keyword arguments for the Task class

methods:
prefect.tasks.core.operators.GetAttr.run (task_result, attr, default=<no default>)[source]
