Code marshalling question.

[Lexy Zhitenev]

Probably you need a 'pickle' or 'cPickle' module?

'marshal' module in python cannot save classes, but pickle does can.

I think the following implementation may do good:


>>> import cPickle, UserDict
>>> class ObjDict(UserDict.UserDict):
...  def __getitem__(self, key):
...   return cPickle.loads(self.data[key])
...  def __setitem__(self, key, value):
...   self.data[key]=cPickle.dumps(value, 1) # true value (1) means binary
format, false - text only

For Python 2.2 implementation may vary: inherit from 'dict' builtin class
and blah-blah-blah

After this you can store objects in this class like in ordinary dictionary.
Dictionary values contain pickled version of your arbitrary data (it cannot
be modules). Then you can take this string representation where you like.
