Solve the following python programming problem given the following code:
def list_formats(self, info_dict) : 
    def line(format, idlen = 20) : 
        return ((('%-' + compat_str ((idlen + 1))) + 's%-10s%-12s%s') % (format ['format_id'], format ['ext'], self.format_resolution (format), self._format_note (format))) 
formats = info_dict.get ('formats', [header_line]) 
    idlen = max (len ('format code'), max ((len (f ['format_id']) for f in formats))) 
    formats_s = [line (f, idlen) for f in formats if ((f.get ('preference') is None) or (f ['preference'] >= (- 1000)))] 
    if (len (formats) > 1) : 
        formats_s [0] += ((' ' if self._format_note (formats [0]) else '') + '(worst)') 
        formats_s [(- 1)] += ((' ' if self._format_note (formats [(- 1)]) else '') + '(best)') 
header_line = line ({ 
        'format_id' : 'format code', 
        'ext' : 'extension', 
        'resolution' : 'resolution', 
        'format_note' : 'note', 
}, idlen = idlen) 
    self.to_screen (('[info] Available formats for %s:
%s
%s' % (info_dict ['id'], header_line, '
'.join (formats_s)))) 

    
    

    Fix the buggy line: formats = info_dict.get ('formats', [header_line])

#Here is Python code to fix the buggy line: formats = info_dict.

formats = info_dict.get ('formats', [info_dict])
