# How to access runtime information

Use the `prefect.runtime` module to access runtime information from within a workflow.

```python theme={null}
from prefect import flow
from prefect.runtime import flow_run


@flow
def moody_workflow(name: str):
    return f"I wish my parents had named me {name} instead of {flow_run.name}."
```

The value of `flow_run.name` will change between workflow runs to match the name of the flow run.

> [!NOTE]
>
> **Attributes of `prefect.runtime` are `None` if a value is not available**
>
> Attributes of `prefect.runtime` will never error when accessed. If a value is not available, the attribute will be `None`.
>
> ```python theme={null}
> from prefect.runtime import flow_run
>
> assert flow_run.name is None
> ```

See the `prefect.runtime` module [reference](/docs/v3/api-ref/python) for all available attributes.
