Convert Param Object to PyDictionary

[PGriffith]

Actually, if you're going that way I kinda prefer @justin.brzozoski's duck-typing approach:

Function to convert json string or python dict into ObjectWrapper

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.
