docs travis coverage

This is a port of the R package taxize. There is a lot going on in the R version of this library, so it will take a while to get all the same functionality over here.

Why? A significant advantage of a Python version of taxize will be for those that are pythonistas at heart. Also, you could use pytaxize in a web app, whereas you could with taxize (e.g., in a Shiny app), but it wouldn't scale, be very fast, etc.

python 2/3

I usually use Python 2.x locally, but I've just been working on making pytaxize compatible with 2.x and 3.x. Please let me know if anything is broken on either version.


sudo pip install git+git://

python or ipython, etc.

import pytaxize

Taxonomic Ids

I've started working on a class interface for taxonomic IDs, which will have a bunch of extension methods to do various things with taxon ids. What's available right now is just getting COL ids.

res = pytaxize.Ids('Poa annua', db='col')

Vascan search

pytaxize.vascan_search(q = ["Helianthus annuus"])
{u'apiVersion': u'0.1',
 u'results': [{u'matches': [{u'canonicalName': u'Helianthus annuus',
     u'distribution': [{u'establishmentMeans': u'introduced',
       u'locality': u'NS',
       u'locationID': u'ISO 3166-2:CA-NS',
       u'occurrenceStatus': u'introduced'},
      {u'establishmentMeans': u'',
       u'locality': u'PE',
       u'locationID': u'ISO 3166-2:CA-PE',
       u'occurrenceStatus': u'excluded'},
      {u'establishmentMeans': u'',
       u'locality': u'NT',
       u'locationID': u'ISO 3166-2:CA-NT',
       u'occurrenceStatus': u'doubtful'},
      {u'establishmentMeans': u'introduced',
