python OrderedDict update a list of keys with the same value -

i trying update list of keys ordereddict same int value, like

for idx in indexes:     res_dict[idx] = value 

where value int variable, indexes list of ints, act keys, res_dict ordereddict, tried resolve above in 1 line,

res_dict[indexes]=value 

but got error:

typeerror: unhashable type: 'list' 

is loop or list comprehension way(s) update here?

the ordereddict (and dict well) provide method update update multiple values @ once.

the pythonic manner want :

res_dict.update((idx, value) idx in indexes) 

it keep original order of ordereddict.
