A list can no be used as the key to a dict, apparently because it is "unhashable": TypeError: unhashable type: 'list'. The code must exist to hash object like this a tuple is hashable and can be constructed from a list. |

As documented, a dict key must be hashable and, because lists are not immutable, they are not hashable and thus can't be used as keys. See the Python Glossary for more info. https://docs.python.org/2/glossary.html |
