I've been reading a little about NumPy arrays and "dtypes" or data-types.

I understand I can create arrays where each element follows a specific
data-type structure.

But, if I create a class, can objects (which are instances) from that class
be elements of a NumPy array?

I mean, can I build a NumPy array whose elements are objects of a class I've
defined?

Sorry if my expressions are not right enough...
