Convert class to Python list

Question

I can't convert a simple [0, 20, 0, 20, 0, 20] to a list.

Code:

geo = hou.pwd().geometry()

print geo.boundingBox()
print type(geo.boundingBox())

Output:

[0, 20, 0, 20, 0, 20]
<class 'hou.BoundingBox'>

Test:

list(geo.boundingBox())
len(geo.boundingBox())

I get the following error:

object BoundingBox is not iterable.
Object of type 'BoundingBox' has no len()

I read all the related questions but they don't seem to solve my problem.

classes may override the __str__() and __repr__() methods to display anything they want. Just because they display to look like a list doesn't mean they are. — President James K. Polk

What are the attributes of hou.BoundingBox? Are you able to get it's size by calling len(geo.boundingBox()) (or similar)? Are you able to index into it (geo.boundingBox()[1])? — inspectorG4dget

@GregS yes, I know what you mean, I tried from string to list but I get the classic : ['[', '0', ',', ' ', '2', '0', ',', ' ', '0', ',', ' ', '2', '0', ',', ' ', '0', ',', ' ', '2', '0', ']'] — Rosenthal

@Neo: If you mean they return BoundingBoxes, no they don't. If you mean they return the same type as each other, I don't see why that matters. — user2357112

Yes, but those are easily convertible to lists, as they support __len__ and __getitem__. Ignacio's answer shows you how. — user2357112

Vector3s can be converted to list since they implement item access methods.

list(geo.boundingBox().minvec()) + list(geo.boundingBox().maxvec())

This does not work you have to call boundingbox first

geo.boundingBox().maxvec()

by saying Item access methods, you mean iterable?
