What's the meaning of dtype=mesh.Mesh.dtype?

[deanhystad]

stl is a package
mesh is a sub-package of stl.
mesh.Mesh is probably a class. You can find out by asking Python. I'm not going to install stl just for this, so I'll use tkinter.ttk as an example.

Output:
>python 
Python 3.10.7 (tags/v3.10.7:6cc6b13, Sep  5 2022, 14:08:36) [MSC v.1933 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> from tkinter import ttk
>>> ttk
<module 'tkinter.ttk' from 'C:\\Program Files\\Python310\\lib\\tkinter\\ttk.py'>
>>> ttk.Checkbutton
<class 'tkinter.ttk.Checkbutton'>

for stl.mess, start up the python interpreter and mport mesh from stl and ask python wht "mesh" is.

Output:
>>> from stl import mesh
>>>mesh

You could even ask for help.
