# Walking Components
This page covers how to walk the Actor Components s in a 3D Level akin to the Details panel:
Compared to the Actor Hierarchy, Components appear deceptively simple to iterate over with a recursive function:
```python
def walk_component(component, indent=2):
"""walk the given component to print its hierarchy"""
print(f"{' '*indent}{component.get_name()}")
# recurse through any immediate children
for child in component.get_children_components(False):
walk_component(child, indent+2)
```
After getting our Actor reference, we can start from the root\_component reference:
```python
EditorActorSubsystem = unreal.get_editor_subsystem(unreal.EditorActorSubsystem)
selection = EditorActorSubsystem.get_selected_level_actors()
actor = selection[0] if selection else None
if actor:
print(actor.get_actor_label())
walk_component(actor.root_component)
```
If we compare the results of this function to the Details Panel, we'll notice quite a few extra lines:
This is because the function\_test Blueprint Asset spawns child actors. If we only want to view the immediate components of our given actor we can add a [get\_owner()](https://docs.unrealengine.com/5.2/en-US/PythonAPI/class/ActorComponent.html#unreal.ActorComponent.get_owner) check to confirm the component is directly managed by the given actor:
```python
def walk_component(component, owner=None, indent=2):
"""walk the given component to print its hierarchy"""
if not component:
return
# validate the component's owner
if not owner:
owner = component.get_owner()
if component.get_owner() != owner:
return
print(f"{' '*indent}{component.get_name()}")
# recurse through any immediate children
for child in component.get_children_components(False):
walk_component(child, owner , indent+2)
```
This added step gives us a printout that better matches the Details Panel:
