Multiple keys per value

Question

Is it possible to assign multiple keys per value in a Python dictionary. One possible solution is to assign value to each key:

dict = {\'k1\':\'v1\', \'k2\':         


        

Answer 1

Using python 2.7/3 you can combine a tuple, value pair with dictionary comprehension.

keys_values = ( (('k1','k2'), 0), (('k3','k4','k5'), 1) )

d = { key : value for keys, value in keys_values for key in keys }

You can also update the dictionary similarly.

keys_values = ( (('k1',), int), (('k3','k4','k6'), int) )

d.update({ key : value for keys, value in keys_values for key in keys })

I don't think this really gets to the heart of your question but in light of the title, I think this belongs here.
