Hi

As far I understand the error happends in this code

Question to Python developers:

As far I understand, index does contain b, and
data does not contain 'b'.

Simple question: why does the line:

  v = self._data[b].get(k, notfound)

throw KeyError at any case? get does have next argument, and if
key is not found, ti will return [], right? 

It seems I do not understand Python code at this place. Please advice. 

Alex

        current = self._getCurrentBucket()
