[issue31730] list unhashable, can not be use as key to dict

[Ned Deily]

Ned Deily <nad at python.org> added the comment:

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
