Solve the following python programming problem given the following code:
def __init__(self, * args, **kwargs) : 
    super (UserSettingsForm, self).__init__ (* args, ** kwargs) 
    def get_language_display_name(code, desc) : 
        try : 
            desc = translation.get_language_info (code) ['name_local'] 
except KeyError : 
            pass 
return ('%s (%s)' % (desc, code)) 
languages = [(k, get_language_display_name (k, v)) for (k, v) in settings.LANGUAGES] 
    self.fields ['language'].choices = languages 
    d = datetime (datetime.today ().year, 1, 1) 
    timezones = [] 
    for tz in pytz.common_timezones : 
        try : 
            utc_offset = pytz.timezone (tz).localize (d).strftime ('%z') 
            utc_offset = (' (UTC %s:%s)' % (utc_offset [: 3], utc_offset [3 :])) 
except Exception : 
            utc_offset = '' 
if (tz != 'UTC') : 
            tz_name = ('%s%s' % (tz, utc_offset)) 
else : 
            tz_name = tz 
timezones.append ((utc_offset, tz_name)) 
self.fields ['timezone'].choices = timezones 

    
    

    Fix the buggy line: timezones.append ((utc_offset, tz_name))

#Here is Python code to fix the buggy line: timezones.

timezones.append ((tz, tz_name))
