After introducing himself and this training course, Sybren shows how to start scripting Blender.
- Introduction
- Computers are stupid
- Using the Python console
- Copying stuff from Blender's user interface
- Changing properties of objects
- Sources of information
Links from the video
- Blender's Python API documentation. This link is for daily builds, so it may be for a newer version of Blender than you're currently using. If you want the documentation for your version of Blender, go to Help → Python API Reference in Blender itself.
- Python Standard Library. Here you can find lots of information about Python itself.

Copy paste while hovering on command is handy indeed. Cool~

For those using it for 2.81, UV Sphere now uses the radius key instead of size
bpy.ops.mesh.primitive_uv_sphere_add(radius=0.1, location=(1, 1, 1))Luciano Muñoz

Using Blender version 2.82 out of the box the python code doesn't show, I had to tick Python Tooltips in menu Edit > Preferences > Interface

I just love this series of video. It's just technical enough not to be boring and still the examples are simple enough to be understandable. Great job. I'm already using all that in my latest project. I'm Done with monkey business !

Very nice indeed. Especially copying from Blender into the search of (Api)the documemtation, is what I did not know , a feature I will use probably a lot.
And congratulations Sybren to your way to giving lessons: Introduction what you will talk about, the talk, AND a recapulation of what has been shown. Great!

copy and paste doesn't work for me. I'm using Blender 2.78c 64 bit in Ubuntu 16.04. Any idea why?

@johantri: What are you doing exactly? Which buttons are you pressing? Where is your mouse cursor when you press them?

Hi Sybren. I've been trying to create a selection box with a file browser and I've had no luck as of yet. I know it's a little more advanced, but would you mind pointing me in the right direction?
Sybren A. Stüvel
24th December 2017 - 15:01
@Pete Robie: The importance here is to think from the data perspective, and not from the GUI perspective. If you want to have a file selector, the property to store the selected file should have
subtype='FILE_PATH'. Blender will draw an appropriate interface for you then.Pete Robie

I get this error:
>>> bpy.data.objects("Cube").location.x Traceback (most recent call last): File "<blender_console>", line 1, in <module> TypeError: 'bpy_prop_collection' object is not callable
>>> bpy.data.objects("Cube").location[0] Traceback (most recent call last): File "<blender_console>", line 1, in <module> TypeError: 'bpy_prop_collection' object is not callable
what am i missing? Blender 2.79b MAC

@Björn Strandberg: You're writing a function call
objects(...)instead of trying to index a collectionobjects[...]-- note the use of parentheses for the former, and brackets for the latter.Björn Strandberg

Should all of this (and the rest of this course) apply to Blender 2.8 Beta (2019-03-03)? Or should I wait for the official release?
Sybren A. Stüvel
12th March 2019 - 09:49
*@Arnar Ómarsson* Much of these techniques will work on 2.8 beta, but there have been significant API changes. With that link you should be able to get quite far, though. Soon I'll start preparing to update things for Blender 2.80; not sure in which form or when that will be available on the Cloud though.

i am copying exactly like you. and i get an IndentationError: unexpected indent
Sybren A. Stüvel
27th September 2020 - 17:14
*@Yule Mayevsky* Python is whitespace-sensitive, so make sure that the indentation is correct and that you're not mixing tabs and spaces.

I have blender 2.9.01. is this course something I can do with it?

at around 4 minutes, manipulating the scale: is it correct that scale multiplication is always done with respect to the original object? in other words, with this example command
bpy.data.objects['Cube'].scale = (0.5, 0.3, 0.2)will it always make the cube the same size, rather than shrinking it from whatever size it is at the moment of executing the command?Julian Darley

at 4.20: auto-completion now uses
tabrather thancontrol space(in B2.90 - not sure about B2.8)Julian Darley

at 6.17, in the Help Menu one can see an Operator Cheat Sheet. clicking on it seems to do nothing, but in fact, a text file has been created and it can be viewed by selecting it in the Text Editor window under the text dropdown (see the text doc icon). if you keep clicking it (as i did before discovering what was happening), you will create more and more copies of the cheat sheet.
