No, reference counting or garbage collection will take care of these for
you.

class spam:
  classVariable1 = "howdy y'all"
  classVariable2 = 22.7
  def __init__(self):
    self.instanceVariable1 = time.time()


All instances of spam will have the same (classVariable1, classvariable2).
Each instance of spam will (generally) have a unique value for
instanceVariable1.
