Hello Patrick and thanks for that tips.

I was wondering, Is there no way to redirect the error output to the internal blender python console? I mean, can use something like the import sys and some sys.stderr = ?

Actually, those modules are imported, but only in the console. There’s also a difference in how they’re imported. The usual way in scripts is to use “import math”, so that you can then use “math.pi” for instance. In this case “from math import *” is used, which puts all members of math in the global namespace. What this means is that instead of “math.pi” you can use just “pi”.

They aren’t imported already. It is just saying those are convenient modules that you may want to use. He had to import math in this example for the math.pi constant. Hope that helps. Happy blending/scripting!

Hey Patrick, in the Blender Python console, it says “Convenience Imports: from mathutils import * ; from math import *

Does this mean those modules are already imported and does not need to import them?
Just curious.
Thanks

Thanks Patrick! Your tutorial was excellent! I learned a lot about Blender python plus your great debugging tips.
Could you do a tutorial about creating user interfaces with Blender python?

Thanks! Haha, yeah, throwing in a couple dozen prints just to know -where- the error is can get quite boring after the first few. =P

Hi Patrick,

This was exactly what I was looking for, I just started python and was playing with blender and got that horrible message check the console for now.. . But now I know which console to use
