# Blender 5.0 Bone Selection in Python
## Three Types of Bones
Blender armatures have three distinct bone data structures accessed differently:[1]
- **Edit Bones** (`bpy.context.object.data.edit_bones`) - Only accessible in Edit-Mode; used for structural changes
- **Bones** (`bpy.context.object.data.bones`) - Accessible in Object/Pose-Mode; read-only properties like head/tail
- **Pose Bones** (`bpy.context.object.pose.bones`) - Contains animation data, constraints, and IK settings
## Selecting Bones
### In Edit-Mode
Set `bone.select = True` on edit bones, then set the active bone using `armature.data.edit_bones.active`:[4]
```python
for bone in arm.data.edit_bones:
if bone.name in bones_to_select:
bone.select = True
if bone.name == bones_to_select[-1]:
arm.data.edit_bones.active = bone
```
### In Pose-Mode
Set the active bone through `armature.data.bones.active` (the Bone object, not the PoseBone):[5]
```python
bone = bpy.context.object.data.bones["Bone"]
bpy.context.object.data.bones.active = bone
```
The active bone in the armature data automatically sets the active pose bone.
## Important Notes
- Mode switching matters: Edit bones don't exist outside Edit-Mode and shouldn't be referenced after leaving that mode[1]
- Pose bones are accessed from the object (`bpy.context.object.pose.bones`), not the armature data, allowing multiple objects to share one armature in different poses[1] |

+The search didn't give me the exact API for selecting bones in pose mode. Let me try a different search specifically for the select property or the new way to select bones in Blender 5.0.

# Blender 5.0 Bone Selection API Changes
In Blender 5.0, there are significant Python API changes related to bone selection state. The key change is that **bone selection state is now stored on the pose bone itself rather than on the bone data**.[4]
## Specific Changes
Previously, you could access selection properties like `select_head` and `select_tail` on bone objects in object mode. However, with the new architecture where selection is stored per pose bone instance, this allows different armature instances to have independent selection states.[4]
## Python API Impact
This represents a **backwards compatibility break** for the Python API.[4] Code that previously used properties like:
```python
bpy.data.armatures["Armature"].bones["Bone.001"].select_tail = True
```
will need to be updated to work with pose bones instead, which now carry the selection state.
## Edit Mode Selection
For selecting bone components in Edit Mode, you should use `EditBone` objects through `bpy.context.object.data.edit_bones`. EditBones have properties for manipulating bone geometry including head and tail positions.[2]
The change reflects Blender 5.0's broader effort to separate selection and visibility states between armature instances, making it possible to work with multiple instances of the same armature simultaneously without their properties being synced.[4] |
