wptools 0.1.5

Wikipedia tools (for Humans)

Python and command-line MediaWiki access for Humans.

• get an HTML or plain text “extract” (lead or summary)

• get a representative image, pageimage, thumbnail

• get an Infobox as a python dictionary

• get any/all Wikidata by title

• get info in any language

• get random info

This package is intended to make it as easy as possible to get data from MediaWiki instances, expose more Wikidata, and extend the MediaWiki API just for kicks. We say “(for Humans)” because that is a goal. Please see NOTES for details. Questions, feedback, and especially contributions are welcome!

Install

Usage

>>> import wptools

An instance can be initialized by:

wptools.page (self)

• None: <NoneType>

• lang: <str> MediaWiki language code (default=’en’)

• title: <unicode> a MediaWiki article title

• wiki: <str> any MediaWiki site

• wikibase: <str> Wikidata entity ID

The simplest way to begin is with a title:

>>> f = wptools.page("Flannery O'Connor")
Flannery_O'Connor (en)
{
  lang: en
  title: Flannery_O'Connor
}

The default language is ‘en’ (English):

>>> t = wptools.page('穐吉敏子')
穐吉敏子 (en)
{
  lang: en
  title: 穐吉敏子
}

Leaving off arguments invokes a random lookup in English:

>>> r = wptools.page()
en.wikipedia.org (action=random) None
Sylvia_Rivera (en)
{
  lang: en
  pageid: 3296309
  title: Sylvia_Rivera
}

If you give only lang, you get a random article in that language:

>>> zh = wptools.page(lang='zh')
zh.wikipedia.org (action=random) None
哈莉特·塔布曼 (zh)
{
  lang: zh
  pageid: 211070
  title: 哈莉特·塔布曼
}

You can also start with a wikibase item:

>>> q = wptools.page(wikibase='Q43303')
Q43303 (en)
{
  lang: en
  wikibase: Q43303
}

Or, another wiki site:

>>> m = wptools.page(wiki='en.wikiquote.org')
en.wikiquote.org (action=random) None
Malala_Yousafzai (en)
{
  lang: en
  title: Malala_Yousafzai
}

Instance attributes echo automatically. You can turn that off with silent=True:

>>> r = wptools.page(silent=True)

Request details echo to stderr with verbose=True:

>>> r = wptools.page(verbose=True)

Examples

Get a representative image:

>>> frida = wptools.page("Frida Kahlo").get_query()
en.wikipedia.org (action=query) Frida_Kahlo
>>> frida.pageimage
u'https://upload.wikimedia.org/wikipedia/commons/0/06/Frida_Kahlo,_by_Guillermo_Kahlo.jpg'

frida.thumbnail

Get a text (or HTML) extract:

>>> ella = wptools.page('Ella Fitzgerald').get_query()
en.wikipedia.org (action=query) Ella_Fitzgerald
>>> print ella.extext
**Ella Jane Fitzgerald** (April 25, 1917 – June 15, 1996) was an
American jazz singer often referred to as the First Lady of Song,
Queen of Jazz and Lady Ella. She was noted for her purity of tone,
impeccable diction, phrasing and intonation, and a "horn-like"
improvisational ability, particularly in her scat singing.
...

>>> print ella.extract
<p><b>Ella Jane Fitzgerald</b> (April 25, 1917 – June 15, 1996) was an

Queen of Jazz and Lady Ella. She was noted for her purity of tone,
impeccable diction, phrasing and intonation, and a "horn-like"
improvisational ability, particularly in her scat singing.</p>
...

Get an Infobox as a python object:

>>> fela = wptools.page('Fela Kuti').get_parse()
en.wikipedia.org (action=parse) Fela_Kuti
>>> fela.infobox['instrument']
'Saxophone, vocals, keyboards, trumpet, guitar, drums'

Get wikidata by title:

>>> fry = wptools.page('Stephen Fry').get_wikidata()
en.wikipedia.org (action=wikidata) Stephen_Fry
en.wikipedia.org (action=wikidata) Q8817795|Q6581097|Q145|Q5
Stephen_Fry (en)
{
  claims: <dict(4)> {Q145, Q5, Q6581097, Q8817795}
  description: English comedian, actor, writer, presenter, and activist
  g_claims: <dict(3)> {info, query, response}
  g_wikidata: <dict(3)> {info, query, response}
  image: https://upload.wikimedia.org/wikipedia/commons/1/15/Stephen_Fry_cropped.jpg
  label: Stephen Fry
  lang: en
  props: <dict(8)> {P18, P21, P27, P31, P345, P569, P856, P910}
  title: Stephen_Fry
  wikibase: https://www.wikidata.org/wiki/Q192912
  wikidata: <dict(8)> {IMDB, birth, category, citizenship, class, ge...
}

Note: Resolved properties and claims are stored in the wikidata attribute. Wikidata claims are processed via WPTools.WIKIPROPS. Properties (e.g. P17: country) are stored in props and those properties that have Wikidata entities for values (e.g. Q142 instead of France) are stored in claims and resolved by another Wikidata API call (as shown above).

Extend Wikidata claims to be resolved:

>>> simone = wptools.page('Simone de Beauvoir')
>>> simone.WIKIPROPS['P21'] = 'gender'
>>> simone.get_wikidata()
en.wikipedia.org (action=wikidata) Simone_de_Beauvoir
en.wikipedia.org (action=wikidata) Q142|Q8745624|Q1214721|Q6581072|Q5
>>> simone.wikidata['gender']
'female'

Get special lead section HTML:

>>> buddha = wptools.page("Buddha").get_rest()
en.wikipedia.org (action=/page/mobile-text/) Buddha
>>> buddha.lead
u'<p heading><a href="https://en.wikipedia.org/wiki/Buddha">Buddh...

<p metadata>Last modified: 2016-09-01T08:15:49Z</p>'

Note: The lead attribute contains the assembled stand-alone, encyclopedia-like HTML fragment:

• <p heading> wiki-linked title and description

• <img {type}> {image, pageimage, or thumbnail}

• <p snipped> lead paragraphs with (noprint, reference, &c.) snipped

• <p metadata> available metadata (e.g. Last modified, coordinates)

Get all the things:

>>> jill = wptools.page('Jill Lepore').get()
en.wikipedia.org (action=query) Jill_Lepore

l'évêché de Toul pour le spirituel (actuellement dans le département
des Vosges en Lorraine), et morte sur le bûcher le 30 mai 1431 à
Rouen, capitale du duché de Normandie alors possession du royaume
d'Angleterre, est une héroïne de l'histoire de France, chef de guerre
