Hi,
you may use e.g. gmtime and only take the hours and minutes part into
account; the drawback is the range calculation in seconds:

>>> [time.strftime("%I:%M%p", time.gmtime(s)) for s in range(0, 86401, 1800)]
['12:00AM', '12:30AM', '01:00AM', '01:30AM', '02:00AM', '02:30AM',
'03:00AM', '03:30AM', '04:00AM', '04:30AM', '05:00AM', '05:30AM',
'06:00AM', '06:30AM', '07:00AM', '07:30AM', '08:00AM', '08:30AM',
'09:00AM', '09:30AM', '10:00AM', '10:30AM', '11:00AM', '11:30AM',
'12:00PM', '12:30PM', '01:00PM', '01:30PM', '02:00PM', '02:30PM',
'03:00PM', '03:30PM', '04:00PM', '04:30PM', '05:00PM', '05:30PM',
'06:00PM', '06:30PM', '07:00PM', '07:30PM', '08:00PM', '08:30PM',
'09:00PM', '09:30PM', '10:00PM', '10:30PM', '11:00PM', '11:30PM',
'12:00AM']
>>>
