At first I did not know about Python “Generator Object” and “yield”, but after I print out the data it is generating inside Blender and turn it into Nodes using Sverchok add-on, things started to make more sense.

Sverchok Add-On itself is actually full of Python generator objects inside it. Same thing with some other Blender tools.

I often take codes for granted, but big kudos to developers out there making tools for artists especially as open source tools.

Enjoy!
