What makes an object uncopyable?

I am trying to make a copy of a certain Python object using the
copy.copy() function. When I try to perform this operation I get an
error like the following:

copy.Error: un(shallow)copyable object of type ...

What factors determine whether an object can be copied?

You are probably trying to copy an instance of a class implemented in
C extension. AFAIK, Python classes have copy support by default, but
extension classes need to implement copy/pickle protocol.
