Hello there,
I have just started to learn python/blender,

Now, in the following text on a property collection definition, the print statement suggests that three values are added while in fact only two are. Unless I am mistaken, but I don't think so.

kind regards,
Ondrej Popp

import bpy

Assign a collection

class SceneSettingItem(bpy.types.PropertyGroup):

name = bpy.props.StringProperty(name="Test Prop", default="Unknown")
value = bpy.props.IntProperty(name="Test Prop", default=22)

bpy.utils.register_class(SceneSettingItem)

bpy.types.Scene.my_settings = \

bpy.props.CollectionProperty(type=SceneSettingItem)

Assume an armature object selected

print("Adding 3 values!")

my_item = bpy.context.scene.my_settings.add()
my_item.name = "Spam"
my_item.value = 1000

my_item = bpy.context.scene.my_settings.add()
my_item.name = "Eggs"
my_item.value = 30

for my_item in bpy.context.scene.my_settings:

print(my_item.name, my_item.value)
