How can I retrieve run results for each task in a multi-task format job run using the Jobs API?
To retrieve run results for each task in a multi-task format job run using the Jobs API, you can follow these steps:

1. Call the `Get a job run` operation (GET /jobs/runs/get) to get the details of the job run.
2. Parse the `tasks` array from the response.
3. Iterate through each of the tasks in the `tasks` array.
4. Parse the `run_id` for each task.
5. Call the `Get the output for a run` operation (GET /jobs/runs/get-output) with the `run_id` to get details on the run for each task.

Here's an example of how you can retrieve run results for each task in a multi-task format job run using the Jobs API:
```python
import requests

# Set the job run ID
job_run_id = 759600

# Set the API endpoint
url = f'https://<databricks-instance>/api/2.0/jobs/runs/get'

# Set the headers
headers = {
    'Authorization': 'Bearer <access-token>',
    'Content-Type': 'application/json'
}

# Set the parameters
params = {
    'run_id': job_run_id
}

# Send the GET request
response = requests.get(url, headers=headers, params=params)

# Parse the JSON response
job_run = response.json()

# Iterate over the tasks in the job run
for task in job_run['tasks']:
    # Parse the run ID for each task
    task_run_id = task['run_id']

    # Set the API endpoint for getting the output of a run
    url = f'https://<databricks-instance>/api/2.0/jobs/runs/get-output'

    # Set the parameters
    params = {
        'run_id': task_run_id
    }

    # Send the GET request
    response = requests.get(url, headers=headers, params=params)

    # Parse the JSON response
    task_run = response.json()

    # Print the task run details
    print(f'Task run ID: {task_run_id}')
    print(f'Task run state: {task_run["state"]}')
    print(f'Task run result state: {task_run["state"]["result_state"]}')
    print()
```
