> Forcing each to the expected type while traversing makes a deep copy: def sanitize\_tree(element): if hasattr(element, '\_\_iter\_\_'): if hasattr(element, 'keys'): return dict((k, sanitize\_tree(element[k])) for k in element.keys()) else: return list(sanitize\_tree(x) for x in element) return element EDIT: Got rid of the unnecessary zip() and used only one keys() iterator instead of two.

(Just stumbled on this thread while researching `remoteServers` and realized I knew a good answer to the question being asked even though it was a bit old... Figured I'd help anyone else who lands here later...)
