It would be nice if it were easier to "look at" multiple pickles in a string using pickletools. The issue is that multiple pickles created using a single pickler share a memo. Some unpickler-like object would be conventient to work with for this case.

Logged In: YES user_id=31435 pickletools.dis() already has an optional memo argument. Do mymemo = {} dis(pickle, memo=mymemo) dis(pickle, memo=mymemo) dis(pickle, memo=mymemo) (for example) to disassemble the first 3 objects in a pickle.

Logged In: YES user_id=3066 Yes, we found that, but it would be nice to have a more convenient interface for it. Note that you're example will still just disassemble the first object 3 times it "pickle" is a string; a fairly trivial convenience object can wrap that with a StringIO so you actually handle subsequent pickles when calling for a disassembly.

Logged In: YES user_id=31435 Well, the module is called pickletools, not pickleeverydamnfoolfunctionicanthinkof . Convenience is for wusses, but you have my blessing if somone wants to bother.

Logged In: YES user_id=3066 There's a reason I assigned it to myself. ;-)

I can't remember why I wanted this; guess this should indeed go in the pickleeverydamnfoolfunctionicanthinkof module, not the standard library.
