Solve the following python programming problem given the following code:
def pureMapping(instance_or_mapping) : 
    def registerMapping(root_module, mapping) : 
        mappings = PureMappingRegistry.mappings.get (root_module) 
        if (mappings is None) : 
            mappings = [] 
            PureMappingRegistry.mappings [root_module] = mappings 
mappings.append (mapping) 
if (inspect.isclass (instance_or_mapping) and issubclass (instance_or_mapping, PureImplementationMapping)) : 
        root_module = instance_or_mapping.__module__.split ('.') [(- 1)] 
        if root_module.startswith ('pure_') : 
            root_module = root_module [len ('pure_') :] 
registerMapping (registerMapping, instance_or_mapping ()) 
        return instance_or_mapping 
def wrap(cls) : 
        module = None 
        if hasattr (instance_or_mapping, '__module__') : 
            module = instance_or_mapping.__module__ 
else : 
            if hasattr (instance_or_mapping, '__class__') : 
                module = instance_or_mapping.__class__.__module__ 
assert (module is not None), ('Using @pureMapping with unsupported object %s' % (instance_or_mapping,)) 
        root_module = module.split ('.') [0] 
        registerMapping (root_module, InstanceMapping (instance_or_mapping, cls)) 
        return cls 
return wrap
