I have 3 objects and want to save in one pickle file.

I used cPickle to dump 3 objects in a pkl file

i.e  cPickle.dump(object1, fileobject,  -1)

                 cPickle.dump(object2, fileobject,  -1)

                 cPickle.dump(object3, fileobject,  -1)

I have changed the 3^rd object and want to save the updated 3^rd object in the pickle file.

I have to dump all the 3 objects again.

Is there any way to dump only the 3^rd object in to the pkl file.

No, there isn't. You could, of course, save each object in its own pickle file. Or use an object database like ZODB instead.
