@cooperspencer Whoops sorry I missed the notification for your comment somehow. The gist was written for python2 since my project ran on Google App Engine which didn't support python3 at the time. FWIW there's a python3 implementation here: nhanb/fundoshi@b367807 . Not sure if it's working anymore though since I haven't touched the code for months.
