def _prep_query(query):
'''Prepare query for Wikipedia. Queries must capitalize (most)
words, must be in unicode, and must not contain characters with
accents (ü). For example, the query http://en.wikipedia.org/wiki/Olga_Kurylenko works,
but the query http://en.wikipedia.org/wiki/olga_kurylenko does not.
Args:
query (str) : Original query
Returns:
Wikipedia-formatted query
'''
# Ensure unicode
query = UnicodeDammit(query).unicode
# Replace accents (ü -> u)
query = geotools.strip_accents(query)
# Split and capitalize query terms
terms = map(
lambda s: s.capitalize() if s not in _no_cap else s,
query.lower().split(' ')
)
# Join query terms
query = ' '.join(terms)
# Return completed query
return query
