Pickle class which create dynamically -

i use py2.7 have read pickle dynamically parameterized sub-class.it places similar question problem more complex.

here more detail code , why use pickle ? or have idea replace apscheduler

i have simplify code.please me. example :

class base(object):     base = none     # has more method , more params in class     def run(self):         print self.base   class a(base):     params = none      def run(self):         print self.base + self.params   class b(base):     params = none      def run(self):         print self.base * self.params   def _create(base_class, p):     class c(base_class):         params = p      return c()   def factory(base_class):     class_list = []     in xrange(0, 500):         class_list.append(_create(base_class, i))     return class_list   try:     import cpickle pickle except importerror:     import pickle  a_class_list = factory(base_class=a) b_class_lsit = factory(base_class=b) in a_class_list:     o = pickle.dumps(a, pickle.highest_protocol)     print o 

error:

cpickle.picklingerror: can't pickle <class '__main__.c'>: attribute lookup __main__.c failed
