I may be misunderstanding you - but it seems you just want to read a
pickle, modify it, and then write it back ?

What you're doing is appending the modified pickle to the original one
- which is more complicated than what you want to achieve.

file_object = open(filename, 'rb')
stored_dict = cPickle.load(file_object)
file_object.close()

... code that modifies stored_dict

file_object = open(filename, 'wb')
cPickle.dump(stored_dict, file_object)
file_object.close()

Any reason why that shouldn't do what you want ?

All the best,
