You can do a recursive descent function, converting to builtin types each step of the way, like this:

>
> 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.
