Taxonomic toolbelt for Python

Project description


docs travis coverage black

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

pytaxize is only developed in and tested with Python 3


Stable from pypi

pip install pytaxize

Development version

sudo pip install git+git://

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.

from pytaxize import Ids
res = Ids('Poa annua')
{'Poa annua': [{'id': '93036',
   'name': 'Poa annua',
   'rank': 'species',
   'uri': ''}]}

Scrape taxonomic names

out = pytaxize.scrapenames(url = '')
[{'verbatim': '(Hemiptera:',
  'scientificName': 'Hemiptera',
  'offsetStart': 222,
  'offsetEnd': 233},
 {'verbatim': 'Sternorrhyncha:',
  'scientificName': 'Sternorrhyncha',
  'offsetStart': 234,
  'offsetEnd': 249},
 {'verbatim': 'Coccoidea:',
  'scientificName': 'Coccoidea',
  'offsetStart': 250,
  'offsetEnd': 260}]
