How to store multiple strings in list in Python?

I have this ListOfCoordinates list with 5 tuples (image below), with each index corresponding to the coordinates of two regions of the brain.

enter image description here

I also have this variable named brain_areas_ROIs, which is a dictionary (image below) with the names of all possible brain regions.

enter image description here

So I want to store in a dictionary the respective brain regions for all the pairs of coordinates obtained, like dict = {0: 'Frontal_Med_Orb_L', 'Frontal_Sup_Medial_L', 1: 'Frontal_Med_Orb_R', 'Frontal_Sup_Medial_L'}, so on and so on.

I'm really lost at this... any ideas?

Thanks in advance!

Does something like this work? I was not sure exactly what kind of variable you wanted. The two variables I used are shortened examples that you can fill with your data.

def main():
    ListOfCoordinates = [
        (2, 4),
        (1, 5),
        (6, 3),
        (7, 0)
    ]

    brain_areas_ROIs = {
        0: "Precentral_L",
        1: "Precentral_R",
        2: "Frontal_Sup_L",
        3: "Frontal_Sup_R",
        4: "Frontal_Sup_Orb_L",
        5: "Frontal_Sup_Orb_R",
        6: "Frontal_Mid_L",
        7: "Frontal_Mid_L"
    }

    print(brain_thing(ListOfCoordinates, brain_areas_ROIs))


def brain_thing(coordinates: list, brain_pos: dict) -> list:
    brain_list = []

    for coordinate in coordinates:
        brain_list.append((brain_pos[coordinate[0]], brain_pos[coordinate[1]]))

    return brain_list
