Solve the following python programming problem given the following code:

    deserialization logic

    format_types = { 
        'json' : 'application/json',

    action_status = (action_status or dict (create = 201, delete = 204)) 
    default_deserializers.update ((deserializers or {

    default_serializers.update ((serializers or { 
        
})) 
    deserializers = controller 
    serializers = default_serializers 
    faults = (faults or {
