Question

I am looking for a data structure in Python that is similar to a dictionary. The difference is that there is two keys. I want to be able to access the value in constant time.
Like:

dict.get(dog, smurf)
{(dog, smurf): 40}

Is this possible?

If this doesn’t exist, I would just do a dictionary in a dictionary. But, the above would be more convenient.

{dog: {(smurf: 40)}}

Answer 1

What’s stopping you?

d = {(dog, smurf): 40}
print d[(dog, smurf)] # 40
