python humanize functions

humanize

This modest package contains various common humanization utilities, like turning a number into a fuzzy human readable duration ('3 minutes ago') or into a human readable size or throughput. It works with python 2.7 and 3.3 and is localized to Russian, French, and Korean.

usage

Integer humanization:

>>> import humanize
>>> humanize.intcomma(12345)
'12,345'
>>> humanize.intword(123455913)
'123.5 million'
>>> humanize.intword(12345591313)
'12.3 billion'
>>> humanize.apnumber(4)
'four'
>>> humanize.apnumber(41)
'41'

Date & time humanization:

>>> import datetime
>>> humanize.naturalday(datetime.datetime.now())
'today'
>>> humanize.naturaldelta(datetime.timedelta(seconds=1001))
'16 minutes'
>>> humanize.naturalday(datetime.datetime.now() - datetime.timedelta(days=1))
'yesterday'
>>> humanize.naturalday(datetime.date(2007, 6, 5))
'Jun 05'
>>> humanize.naturaldate(datetime.date(2007, 6, 5))
'Jun 05 2007'
>>> humanize.naturaltime(datetime.datetime.now() - datetime.timedelta(seconds=1))
'a second ago'
>>> humanize.naturaltime(datetime.datetime.now() - datetime.timedelta(seconds=3600))
'an hour ago'

Filesize humanization:

>>> humanize.naturalsize(1000000)
'1.0 MB'
>>> humanize.naturalsize(1000000, binary=True)
'976.6 KiB'
>>> humanize.naturalsize(1000000, gnu=True)
'976.6K'

Human readable floating point numbers:

>>> humanize.fractional(1/3)
'1/3'
>>> humanize.fractional(1.5)
'1 1/2'
>>> humanize.fractional(0.3)
'3/10'
>>> humanize.fractional(0.333)
'1/3'
>>> humanize.fractional(1)
'1'

Localization

How to change locale in runtime

>>> print humanize.naturaltime(datetime.timedelta(seconds=3))
3 seconds ago
>>> _t = humanize.i18n.activate('ru_RU')
>>> print humanize.naturaltime(datetime.timedelta(seconds=3))
3 секунды назад
>>> humanize.i18n.deactivate()
>>> print humanize.naturaltime(datetime.timedelta(seconds=3))
3 seconds ago

You can pass additional parameter path to :func:`activate` to specify a path to search locales in.

>>> humanize.i18n.activate('pt_BR')
IOError: [Errno 2] No translation file found for domain: 'humanize'
>>> humanize.i18n.activate('pt_BR', path='path/to/my/portuguese/translation/')
<gettext.GNUTranslations instance ...>

How to add new phrases to existing locale files

$ xgettext -o humanize.pot -k'_' -k'N_' -k'P_:1c,2' -l python humanize/*.py  # extract new phrases
$ msgmerge -U humanize/locale/ru_RU/LC_MESSAGES/humanize.po humanize.pot # add them to locale files
$ msgfmt --check -o humanize/locale/ru_RU/LC_MESSAGES/humanize{.po,.mo} # compile to binary .mo

How to add new locale

$ msginit -i humanize.pot -o humanize/locale/<locale name>/LC_MESSAGES/humanize.po --locale <locale name>

Where <locale name> is locale abbreviation, eg 'en_GB', 'pt_BR' or just 'ru', 'fr' etc.
