1) Обычное форматирование (числовое или прописью на английском):

from datetime import datetime

dt = datetime.now()

# 1) str.format

strg = '{:%B %d, %Y}'.format(dt)

print(strg) # July 22, 2017

# 2) datetime.strftime

strg = dt.strftime('%B %d, %Y')

print(strg) # July 22, 2017

# 3) f-strings in python >= 3.6

strg = f'{dt:%B %d, %Y}'

print(strg) # July 22, 2017

2) Представление прописью на русском языке (взято отсюда: https://ru.stackoverflow.com/a/623845 ):

#!/usr/bin/env python3

import pendulum # $ pip install pendulum

d = pendulum.from_format('01.07.2009', '%d.%m.%Y')

ordinal_day_word = ['', 'первое', 'второе', 'третье', ...][d.day]

print(ordinal_day_word + d.format(' %B %Y года', locale='ru'))

# -> первое июля 2009 года

3) Получить дату в локализированном формате для определенного языка:

>>> import time

>>> print time.strftime("%a, %d %b %Y %H:%M:%S")

Sun, 23 Oct 2005 20:38:56

>>> import locale

>>> locale.setlocale(locale.LC_TIME, "sv_SE") # swedish

'sv_SE'

>>> print time.strftime("%a, %d %b %Y %H:%M:%S")

Нужно быть внимательным с локалями, потому что на Linux/Unix и Windows они записываются по-разному . Кроме того, команда смены локали глобальна для программы и может поменять поведение в неожиданных местах. Чтобы этого избежать, можно воспользоваться локализирующими библиотеками, типа babel:

>>> from datetime import date, datetime, time

>>> from babel.dates import format_date, format_datetime, format_time

>>> d = date(2007, 4, 1)

>>> format_date(d, locale='en')

u'Apr 1, 2007'

>>> format_date(d, locale='de_DE')

u'01.04.2007'
