# JobCache.group

```python
def JobCache.group(name: str) -> JobCache
```

You can nest caches in a hierarchical manner using [groups](/docs/workflows/run-and-inspect/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

**name**

`str`

The name of the cache group.

```python title="Python"
# 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"]
```
