Hello World

Let's create your first Graflow workflow.

Install Graflow​

pip install graflow

Your First Task​

Create a file called hello.py:

from graflow import task

@task
def hello():
    print("Hello, Graflow!")
    return "success"

if __name__ == "__main__":
    result = hello.run()
    print(f"Task completed with result: {result}")

Run it:

python hello.py

You should see:

Hello, Graflow!
Task completed with result: success

Your First Workflow​

Now let's chain multiple tasks into a workflow. Create pipeline.py:

from graflow import task, workflow

with workflow("simple_pipeline") as wf:

    @task
    def start():
        print("Starting!")

    @task
    def middle():
        print("Middle!")

    @task
    def end():
        print("End!")

    # Define sequential pipeline: start -> middle -> end
    start >> middle >> end

    # Execute the workflow
    wf.execute()

Run it:

python pipeline.py

You should see:

Starting!
Middle!
End!

The >> operator chains tasks sequentially — middle runs after start, and end runs after middle.
