How can I search for multiple specific keys with specific values in a nested dictionary?

Question

I have this dictionary in my Python code:

LOCATIONS = {
    1: {
        "Name": "West of house",
        "x": 0, "y": 0, "z": 0,
    },
    2: {
        "Name": "Test Location",
        "x": 0, "y": 0, "z": 0,
    }
}

How can I check the current values of x, y, and z and match them to a location and get its name?

Rethink your container and use a dictionary with a tuple of the coordinates as key. This will be **much** more efficient — mozway, Dec 13 '21 at 21:23
Use a loop that checks whether `x, y, z` contain the searched values. — Barmar, Dec 13 '21 at 21:25
Not sure I understood the question, are you asking how to access a value in a dictionary? — David Wer, Dec 13 '21 at 21:25
what do the keys 1 and 2 represent? would it not make more sense having a list of dictionaries? — Sayse, Dec 13 '21 at 21:27

Do you want something like this?:

name = None
for values in LOCATIONS.values():
    if (values["x"], values["y"], values["z"]) == (0, 0, 0):
        name = values["Name"]

Keep in mind that if there are multiple names, that have the same x, y & z then the last one will be the output. If you want all of them then you should store them in a container like a list.
