Question

Using Python, I have created a list that is indexed by a tuple:

return values[(a, b)]

However, sometimes I want to pass in (a, _) where I don’t care what the value of b is and receive a list of all the possible indices.

Such as:

values[(dog, _)] => returns [(dog, Mike), (dog, Sam), (dog, Edward)]

Is this possible in Python?

Answer 1

You must use the exact value of a key to index a dictionary.

To find multiple keys, you need to loop over them:

[k for k in my_dict if k[0] == dog]
