gw2api is a Python library to interface with the Guild Wars 2 API. It aims to have an almost one-to-one mapping to the JSON API, with only some minor differences.
import gw2api.v2
for item in gw2api.v2.items.get(range(30684, 30705)):
link = gw2api.encode_item_link(item["id"])
print "%-26s %-9s %-10s %s" % (item["name"], item["rarity"],
item["details"]["type"], link)
gw2api is available from the Python Package Index and is hosted on GitHub.
