Is my thinking Pythonic?

[Craig Allen]

generally, I name the members in the Class definition and set them to
None there...

class Car:
   speed = None
   brand = None

   def __init__():
      self.speed = defaultspeed #alternately, and more commonly, get
this speed as a initializer argument
      self.brand = defaultbrand


That solves the issue of being able to "see" all the members of an
object by reading code... however, this all goes out the window when
composing an instance dynamically (i.e. metaclass type stuff).
