You can set dynamic attributes on class objects without any special
processing at all.  Just do it, like so:

  class X(object):
    pass

  myx = X()

  myx.color = 'red'
  myx.food = 'french fries'
  myx.lucky_number = 7

Or, if you don't know the attribute name beforehand:

  setattr(myx, 'occupation', 'programmer') 

For methods, use an existing method name (without the trailing parentheses)
as the attribute value, like so:

  myx.method = float # assigns the built-in method float()
