I've got a huge list of date-times like this as strings:

Jun 1 2005  1:33PM
Aug 28 1999 12:00AM

I'm going to be shoving these back into proper datetime fields in a database so I need to magic them into real datetime objects.

This is going through Django's ORM so I can't use SQL to do the conversion on insert.


Converting string into datetime, Using this module, we can easily parse any date-time string and convert it to a datetime object. Converting Strings Using datetime. The datetime module consists of  Summary: in this tutorial, you will learn how to convert a string to a datetime in SQL Server using the CONVERT () and TRY_CONVERT () function. SQL Server provides the CONVERT () function that converts a value of one type to another: Besides the CONVERT () function, you can also use the TRY_CONVERT () function:


Use the third party dateutil library:

from dateutil import parser
parser.parse("Aug 28 1999 12:00AM")  # datetime.datetime(1999, 8, 28, 0, 0)

It can handle most date formats, including the one you need to parse. It's more convenient than strptime as it can guess the correct format most of the time.

It's very useful for writing tests, where readability is more important than performance.

You can install it with:

pip install python-dateutil

Converting Strings to datetime in Python, Convert.ToDateTime(String), DateTime.Parse() and DateTime.ParseExact() methods for converting a string-based date to a System.DateTime object, Convert​  C# DateTime is a struct type, which is mostly used in applications to manage date, date-time, time data types. Most of time, we get a date in form of a string and we usually need to parse to a DateTime object to perform some operations like date difference, weekday, month name, formatting and so on.


Check out strptime in the time module. It is the inverse of strftime.

$ python
>>> import time
>>> time.strptime('Jun 1 2005  1:33PM', '%b %d %Y %I:%M%p')
time.struct_time(tm_year=2005, tm_mon=6, tm_mday=1,
                 tm_hour=13, tm_min=33, tm_sec=0,
                 tm_wday=2, tm_yday=152, tm_isdst=-1)

Python string to datetime - strptime(), Learn techniques to parse strings that represent dates and times to create a DateTime from the date and time string.

I have put together a project that can convert some really neat expressions. Check out timestring.

Here are some examples below:
pip install timestring
>>> import timestring
>>> timestring.Date('monday, aug 15th 2015 at 8:40 pm')
<timestring.Date 2015-08-15 20:40:00 4491909392>
>>> timestring.Date('monday, aug 15th 2015 at 8:40 pm').date
datetime.datetime(2015, 8, 15, 20, 40)
>>> timestring.Range('next week')
<timestring.Range From 03/10/14 00:00:00 to 03/03/14 00:00:00 4496004880>
>>> (timestring.Range('next week').start.date, timestring.Range('next week').end.date)
(datetime.datetime(2014, 3, 10, 0, 0), datetime.datetime(2014, 3, 14, 0, 0))

How to Convert String to DateTime in C# and VB.Net, of date. In this scenario we need to convert string value to DateTime object and then use WeekDay property(obj.WeekDay) to find out week day. So if you need to convert a string to a date/time value, you can use the CONVERT() function or the CAST() function. And if you get an error while using those two functions, the PARSE() function might be just what you need. This article contains examples using the CAST() function.


Remember this and you didn't need to get confused in datetime conversion again.

String to datetime object = strptime

datetime object to other formats = strftime

Jun 1 2005 1:33PM

is equals to

%b %d %Y %I:%M%p

%b Month as locale’s abbreviated name(Jun)

%d Day of the month as a zero-padded decimal number(1)

%Y Year with century as a decimal number(2015)

%I Hour (12-hour clock) as a zero-padded decimal number(01)

%M Minute as a zero-padded decimal number(33)

%p Locale’s equivalent of either AM or PM(PM)

so you need strptime i-e converting string to

>>> dates = []
>>> dates.append('Jun 1 2005  1:33PM')
>>> dates.append('Aug 28 1999 12:00AM')
>>> from datetime import datetime
>>> for d in dates:
...     date = datetime.strptime(d, '%b %d %Y %I:%M%p')
...     print type(date)
...     print date
... 

Output

<type 'datetime.datetime'>
2005-06-01 13:33:00
<type 'datetime.datetime'>
1999-08-28 00:00:00

What if you have different format of dates you can use panda or dateutil.parse

>>> import dateutil
>>> dates = []
>>> dates.append('12 1 2017')
>>> dates.append('1 1 2017')
>>> dates.append('1 12 2017')
>>> dates.append('June 1 2017 1:30:00AM')
>>> [parser.parse(x) for x in dates]

OutPut

[datetime.datetime(2017, 12, 1, 0, 0), datetime.datetime(2017, 1, 1, 0, 0), datetime.datetime(2017, 1, 12, 0, 0), datetime.datetime(2017, 6, 1, 1, 30)]
