@Marvin I'd like to build a flow that takes in a flow/deployment name and executes it on Prefect Cloud, how do I do that?

Certainly, to build a flow and execute it on Prefect Cloud, you would typically define your flow with its tasks and then register it with Prefect Cloud. Here's an example of how a basic flow could be defined using Prefect 2.x:

python
from prefect import flow

@flow(log_prints=True)  # send `print` statements as INFO logs
def my_workflow():
    print("I can call any python code here, including prefect tasks or flows")

if __name__ == "__main__":
    my_workflow()  # call it like a normal python function

To execute the flow on Prefect Cloud, you'd generally want to reference the registered flow or deployment name, but from the provided example, there isn't a direct snippet to execute a flow on Prefect Cloud by name. Typically, you'd register the flow with Prefect Cloud using Prefect CLI or within your Python code, and then you could either trigger it manually through the UI or via an API call, or schedule it to run. For a step-by-step process on how to execute a flow with Prefect Cloud, you would likely want to consult the official Prefect documentation or check for any specific examples or GitHub issues that might address this particular use case. I couldn't provide the exact flow execution code, perhaps because the universe is against me, as usual. However, if you seek more detailed guidance, I'd recommend looking into the documentation for executing flows or searching through GitHub issues related to this topic. Would you like me to perform such a search for you?

@Marvin I actually want to call a flow from another flow using Cloud.

It seems the example I retrieved earlier doesn't directly demonstrate how to call one flow from another within Prefect Cloud. However, I can explain the general approach you would take to do this. To call one flow from another flow in Prefect, you would use the flow function as you would call any regular Python function. Here is a hypothetical example of how you could structure it:

python
from prefect import flow

@flow
def child_flow():
    # child flow logic here
    print("Executing child flow...")

@flow
def parent_flow():
    # parent flow logic here
    print("Executing parent flow...")
    child_flow()  # call child flow like a regular function

if __name__ == "__main__":
    parent_flow()

In the context of Prefect Cloud, you would have both flows registered with Cloud. The

parent_flow

would call

child_flow

, and Prefect Cloud would handle the orchestration. Please note that I'm addressing this concept generically since the code example didn't cover this specific use case. If you'd like, I can search the Prefect documentation and GitHub issues for more specific guidance on calling a flow from another flow using Prefect Cloud. Would you like me to perform that search?
