[New-bugs-announce] [issue31730] list unhashable, can not be use as key to dict

[gene@nlc.co.nz]

New submission from gene at nlc.co.nz <gene at nlc.co.nz>:

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.
