There is an error in the current version of the python API Wikipedia library. You can install the lucasdnd branch on github that fixed this:
pip install git+https:
(You can --upgrade if you already installed it)
Now:
>>> import wikipedia >>> ny = wikipedia.page("New York") >>> ny.sections [u'History', u'16th century', u'17th century', u'18th century, the American Revolution, and statehood', u'19th century', u'Immigration', u'September 11, 2001 attacks', u'Hurricane Sandy, 2012', u'Geography', u'Climate', u'Statescape', u'Regions', u'Adjacent geographic entities', u'State parks', u'National parks', u'Administrative divisions', u'Demographics', u'Population', u'Most populous counties', u'Major cities', u'Metropolitan areas', u'Racial and ancestral makeup', u'Languages', u'Religion', u'LGBT', u'Economy', u'Wall Street', u'Silicon Alley', u'Microelectronic hardware and photographic processing', u'Media and entertainment', u'Tourism', u'Exports', u'Education', u'Transportation', u'Government and politics', u'Government', u'Capital punishment', u'Federal representation', u'Politics', u'Sports', u'See also', u'References', u'Further reading', u'External links']
Most likely, it will be fixed in the main library in the near future.
