If you try the following:
from pytaxonomies import Taxonomies
taxonomies = Taxonomies()
taxonomies.get("c").machinetags_expanded()
you get:
ile "<ipython-input-13-21c1a4715166>", line 1, in <module>
taxonomies.get("c").machinetags_expanded()
AttributeError: 'NoneType' object has no attribute 'machinetags_expanded'
Imho I would expect all circl results (as it starts with c) or a proper error message or introduce a new method:
from pytaxonomies import Taxonomies
taxonomies = Taxonomies()
taxonomies.search("c").machinetags_expanded()
And then return the closest match (but then I would love it also searching not only in the keys but also values)
Hope that make sense.
