Catching KeyError instead of IndexError

[kootenpv]

For example:

I created some indexed objects, but in the case one does not exist and one tries to use "single" (index['user_id']["1"].single), the following happens:

/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/site-packages/neo4jrestclient/iterable.py in single(self)
     65     def single(self):
     66         try:
---> 67             return self[0]
     68         except KeyError:
     69             return None

/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/site-packages/neo4jrestclient/iterable.py in __getitem__(self, index)
     29 
     30     def __getitem__(self, index):
---> 31         elto = super(Iterable, self).__getitem__(index)
     32         if self._attribute:
     33             return self._class(elto[self._attribute], update_dict=elto,

IndexError: list index out of range

We can see the code here:

I think what is meant is catching an IndexError rather than KeyError. Could that be the case?

Yes, probably better to catch both. Thanks!
