How to get date format from a date string?

Question

I use dateparser.parse to turn a string date into a datetime object:

>>> dateparser.parse(u'22 Décembre 2010')
datetime.datetime(2010, 12, 22, 0, 0)

But now I want to create new dates with the same string format. How can I get this?

>>> get_date_pattern(u'22 Décembre 2010')
'%d %B %Y'

Edit: I'll clarify that I don't know what the string format is (I'm iterating through a list of many date strings, and for each one I want to create a new date in the same format). I'm not looking to convert a datetime object to string, I'm looking to take a formatted string and determine what that format is.

Answer 1

You can use a 3rd party lib dateutil.

from dateutil import parser
dt = parser.parse("06 April, 2019")

To install this, you can do:

pip install python-dateutil

Answer 2

From the datetime documentation:

datetime.strftime(format)

Return a string representing the date and time, controlled by an explicit format string. For a complete list of formatting directives, see section strftime() and strptime() Behavior.
