Personally, though, I don't see *that* much wrong with

partner_id = values['partner_id']
product_id = values['product_id']
ship_to = values['ship_to']
product_ids = values['product_ids']

It's a bit repetitive, and maybe a little verbose, but nothing a good

wouldn't make straightforward to manage.

Could we use semicolons in the subscript to create a tuple? They could be used for packing or unpacking:

partner_id, product_id, ship_to, product_ids = values['partner_id'; 'product_id'; 'ship_to'; 'product_ids']

my_dict['partner_id'; 'product_id'; 'ship_to'; 'product_ids'] = partner_id, product_id, ship_to, product_ids

Instead of special syntax, what if dict.values() returned a tuple when given keys as arguments:

partner_id, product_id, ship_to, product_ids = my_dict.values('partner_id', 'product_id', 'ship_to', 'product_ids')

That avoids repeating the dict variable, at least. And as there is dict.update(), I don't see the need for a new syntax for assigning to multiple keys.
