Question

Answer 1

Load the string into a datetime object via strptime() , then dump via strftime() in the desired format:

>>> from datetime import datetime
>>> d = datetime.now().strftime("%Y-%m-%d %H:%M:%S")
>>> d  # d is a string
'2016-04-28 07:46:32'
>>> datetime.strptime(d, "%Y-%m-%d %H:%M:%S").strftime("%Y-%m-%d %I:%M:%S %p")
'2016-04-28 07:46:32 AM'

Note that the %I here is a 12-hour clock .

Answer 2

24 hour to 12-hour

>>> from datetime import datetime
>>> datetime.strptime('2016-05-25 13:45:56', '%Y-%m-%d %H:%M:%S')
datetime.datetime(2016, 5, 25, 13, 45, 56)
>>> dt=datetime.strptime('2016-05-25 13:45:56', '%Y-%m-%d %H:%M:%S')
>>> dt.strftime('%Y-%m-%d %I:%M:%S %p')
'2016-05-25 01:45:56 PM'
>>> 

12-hour to 24-hour

>>> dt=datetime.strptime('2016-05-25 01:45:56 PM', '%Y-%m-%d %I:%M:%S %p')
>>> dt
datetime.datetime(2016, 5, 25, 13, 45, 56)
>>> dt.strftime('%Y-%m-%d %H:%M:%S')
'2016-05-25 13:45:56'
>>>
