# unmap\_attr

Unmaps an attribute name from the other attribute name. Nothing is returned.

Any attribute name that is currently mapped to another attribute name (See [map\_attr](/docs/maci/object/methods/map_attr.md)) can be unmapped using this method. Attribute names must already exist to unmap them.

This will release the mapping between a child attribute name and the corresponding parent attribute name. In addition, If a parent attribute name is specified, that contains children with references to it, all child mappings will be detached from that parent<br>

*Basic Example of unmapping a name using default positional parameter*

```python
data.unmap_attr('attr_name')
```

In this example, we simply unmap an attribute name that already exists in the [MaciDataObj](/docs/maci/object.md) and is also currently present in the reference maps by passing a string of the attribute name as an argument to the unmap\_attr method to unmap the name.
