Solve the following python programming problem given the following code:
@ classmethod 
def _pull_all(cls, args) : 
    api._timeout = cls.timeout 
    def _title_to_filename(title) : 
        no_punct = ''.join ([c for c in title.lower () if (c.isalnum () or (c in [' ', '_', '-']))]) 
        return no_punct.replace (' ', '_').replace ('-', '_').strip ('_') 
format = args.format 
    res = api.Timeboard.get_all () 
    report_warnings (res) 
    report_errors (res) 
    if (not os.path.exists (args.pull_dir)) : 
        os.mkdir (args.pull_dir, 493) 
used_filenames = set () 
    for dash_summary in res ['dashes'] : 
        filename = _title_to_filename (dash_summary ['title']) 
        if (filename in used_filenames) : 
            filename = ((filename + '-') + dash_summary ['id']) 
used_filenames.add (filename) 
        cls._write_dash_to_file (dash_summary ['id'], os.path.join (args.pull_dir, (filename + '.json')), args.timeout, format, args.string_ids) 
if (format == 'pretty') : 
        print ('
### Total: {0} dashboards to {1} ###'.format (len (used_filenames), os.path.realpath (args.pull_dir))) 

    
    

    Fix the buggy line: api._timeout = cls.timeout
assistant
#Here is Python code to fix the buggy line: api.

api._timeout = args.timeout
