From DatetimeIndex to list of times

My objectif is to have a lists of times (in seconds), already packaged in lists of times in 5 minutes for a whole day.
This is my code to package the whole day of "2016-07-08" by 5 minutes :

pd.date_range('2016-07-08 00:00:00', '2016-07-08 23:59:00', freq='5Min')


The result :

DatetimeIndex(['2016-07-08 00:00:00', '2016-07-08 00:05:00',
'2016-07-08 00:10:00', '2016-07-08 00:15:00',
'2016-07-08 00:20:00', '2016-07-08 00:25:00',
'2016-07-08 00:30:00', '2016-07-08 00:35:00',
'2016-07-08 00:40:00', '2016-07-08 00:45:00',
...
'2016-07-08 23:10:00', '2016-07-08 23:15:00',
'2016-07-08 23:20:00', '2016-07-08 23:25:00',
'2016-07-08 23:30:00', '2016-07-08 23:35:00',
'2016-07-08 23:40:00', '2016-07-08 23:45:00',
'2016-07-08 23:50:00', '2016-07-08 23:55:00'],
dtype='datetime64[ns]', length=288, freq='5T')


And this is the code to have all times (by second) included in every 5 minutes:

for time in pd.date_range('2016-07-08 00:00:00', '2016-07-08 23:59:00', freq='5Min').tolist():
time_by_5_min = datetime.datetime.strftime(time.to_datetime(), "%Y-%m-%d %H:%M:%S")
print pd.date_range(time_by_5_min, freq='S', periods=60)


The result :

dtype='datetime64[ns]', freq='S')
etc


This is perfect for me!
I want now to have lists, not a pandas.tseries.index.DatetimeIndex..
The .tolist() method give this :

for time in pd.date_range('2016-07-08 00:00:00', '2016-07-08 23:59:00', freq='5Min').tolist():
time_by_5_min = datetime.datetime.strftime(time.to_datetime(), "%Y-%m-%d %H:%M:%S")
print (pd.date_range(time_by_5_min, freq='S', periods=60)).tolist()


The result :

[Timestamp('2016-07-08 00:00:00', offset='S'), Timestamp('2016-07-08 00:00:01', offset='S'), Timestamp('2016-07-08 00:00:02', offset='S'), Timestamp('2016-07-08 00:00:03', offset='S'), Timestamp('2016-07-08 00:00:04', offset='S'), Timestamp('2016-07-08 00:00:05', offset='S'), Timestamp('2016-07-08 00:00:06', offset='S'), etc]


I want to have something like this :

Any ideas ?

Answer

I think you can use DatetimeIndex.strftime:

I try remove some code (in sample is not necessary, maybe in real code is important)

for time in pd.date_range('2016-07-08 00:00:00', '2016-07-08 23:59:00', freq='5Min'):    
    print (pd.date_range(time, freq='S', periods=60).strftime("%Y-%m-%d %H:%M:%S").tolist())
['2016-07-08 00:00:00', '2016-07-08 00:00:01', '2016-07-08 00:00:02', '2016-07-08 00:00:03', '2016-07-08 00:00:04', '2016-07-08 00:00:05', '2016-07-08 00:00:06', '2016-07-08 00:00:07', '2016-07-08 00:00:08', '2016-07-08 00:00:09', '2016-07-08 00:00:10', '2016-07-08 00:00:11', '2016-07-08 00:00:12', '2016-07-08 00:00:13', '2016-07-08 00:00:14', '2016-07-08 00:00:15', '2016-07-08 00:00:16', '2016-07-08 00:00:17', '2016-07-08 00:00:18', '2016-07-08 00:00:19', '2016-07-08 00:00:20', '2016-07-08 00:00:21', '2016-07-08 00:00:22', '2016-07-08 00:00:23', '2016-07-08 00:00:24', '2016-07-08 00:00:25', '2016-07-08 00:00:26', '2016-07-08 00:00:27', '2016-07-08 00:00:28', '2016-07-08 00:00:29', '2016-07-08 00:00:30', '2016-07-08 00:00:31', '2016-07-08 00:00:32', '2016-07-08 00:00:33', '2016-07-08 00:00:34', '2016-07-08 00:00:35', '2016-07-08 00:00:36', '2016-07-08 00:00:37', '2016-07-08 00:00:38', '2016-07-08 00:00:39', '2016-07-08 00:00:40', '2016-07-08 00:00:41', '2016-07-08 00:00:42', '2016-07-08 00:00:43', '2016-07-08 00:00:44', '2016-07-08 00:00:45', '2016-07-08 00:00:46', '2016-07-08 00:00:47', '2016-07-08 00:00:48', '2016-07-08 00:00:49', '2016-07-08 00:00:50', '2016-07-08 00:00:51', '2016-07-08 00:00:52', '2016-07-08 00:00:53', '2016-07-08 00:00:54', '2016-07-08 00:00:55', '2016-07-08 00:00:56', '2016-07-08 00:00:57', '2016-07-08 00:00:58', '2016-07-08 00:00:59']
