Use Babel:

>>> import babel.dates
>>> import datetime
>>> now = datetime.datetime.now()

6 września 2010

E
Month, locale specific alternative representation usually used for long date representation.

If you want to specify format in your html template then this will do:
{{ datefield|date:"j E Y" }}

OP's code now works as he intended: returning '30 kwietnia 2020' and not 30 kwiecień 2020. Tested today with Python 2.7 and Python 3.6. Setting locale was required, I used the platform one - this might be an issue with web-apps as per other answers.

datetime.datetime(2020, 4, 30, 18, 13, 21, 308217)

'30 April 2020'
>>> import locale
>>> locale.setlocale(locale.LC_ALL, '')
'pl_PL.UTF-8'
