# JobCache.group

```python theme={"system"}
def JobCache.group(name: str) -> JobCache
```

You can nest caches in a hierarchical manner using [groups](/workflows/caches#groups-and-hierarchical-keys).
Groups are separated by a forward slash (/) in the key. This hierarchical structure functions similarly to a file system.

## Parameters

<ParamField path="name" type="str">
  The name of the cache group.
</ParamField>

<RequestExample>
  ```python Python theme={"system"}
  # within a Tasks execute method, access the job cache
  # def execute(context: ExecutionContext)
  cache = context.job_cache

  # use groups to nest related cache values
  group = cache.group("some-group")
  group["value"] = b"my-value"

  nested = group.group("nested")
  nested["value"] = b"nested-value"

  # access nested groups directly via / notation
  value = cache["some-group/nested/value"]
  ```
