@Marvin how do I run a task from task?

In order to run a task from another task in Prefect, you can use the

.submit()

method to queue up tasks within a flow, enabling one task to trigger the execution of another. Here's a simplified example from the documentation:

python
from prefect import flow, task

@task
def say_hello(name):
    print(f"Hello {name}")

@task
def say_goodbye(name):
    print(f"Goodbye {name}")

@flow
def greetings(names):
    for name in names:
        say_hello.submit(name)
        say_goodbye.submit(name)

if __name__ == "__main__":
    greetings(["arthur", "trillian", "ford", "marvin"])

In this code snippet, the

greetings

flow triggers the

say_hello

and

say_goodbye

tasks for each provided name. Tasks are submitted for execution with the

submit

method inside the flow definition. You can find more detailed information and examples in the Prefect documentation.
