How to send a Signal-With-Start in Python

To send a Signal-With-Start in Python, use the start_workflow() method and pass the start_signal argument with the name of your Signal, instead of using a traditional Workflow start.

async def main():
    client = await Client.connect("localhost:7233", namespace="your-namespace")

    handle = await client.start_workflow(
        "your-workflow-name",
        "some arg",
        id="your-workflow-id",
        task_queue="your-task-queue",
        start_signal="your-signal-name",
    )
