Solve the following python programming problem given the following code:
@ staticmethod 
def _dump_data(obj_response, files, form_values, container_id) : 
    def dump_files() : 
        if ('file' not in files) : 
            return 'Bad upload' 
file_data = files ['file'] 
        file_name = file_data.filename 
        if (file_name is None) : 
            return 'Nothing uploaded' 
file_type = file_data.content_type 
        file_size = len (file_data.read ()) 
        return ('Uploaded file %s (%s) - %sB' % (file_name, file_type, file_size)) 
html = 'Form values: %s<hr />Files: %s' 
    html = (html % (str (files), dump_files ())) 
    obj_response.html (('#%s' % container_id), html) 

    
    

    Fix the buggy line: html = (html % (str (files), dump_files ()))
