Python dict with int entries comparison with int?

Good evening! I am trying to figure out how to compare a variable with the int entries in a dictionary. I am programming an arcade game and I have x and y coordinates stored in a dict (x:y) and playerx and playery variables. I would like to make a comparison so that if the player ever reaches coordinates specified in the dict, it would do something. How could I go about doing this?

I imagine something along the lines of:

if playerx in dict:
    if playery in dict[x]:
        dosomething()

But I cannot quite figure out how to do it properly.

given the speed of dictionaries its a very fast python data structure. but if you want to really visualize coordinates intuitively , try creating a spatial(x,y) tuple. assuming all locations are managed properly by your game scheme.

#Code
d={"VillageLocation":(1,1)}
player1_location=(1,1)
player2_location=(2,2)
#check by values
reachedVillage = player1_location in d.values() #returns True #method for checking by values
if (reachedVillage == True):
    goToSleep("player1")

Explanation: Player 1 will now go to sleep because player1's location and village location now match which is stored as 'True' in the "reachedVillage "variable.

Trick Used: checking in dictionary by values instead of keys.

Perhaps this is what you need:

player=(0,1)

your_dict = {0:1,1:2,2:3}

if player[0] in your_dict:
    if player[1] == your_dict[player[0]]:
        print("hello, is it me you're looking for?")

Maybe you can use a list of tuples

l_coord = [(1, 2), (2, 3), (4, 5)]
player_x = 2
player_y = 3
player = (player_x, player_y)
if player in l_coord:
    print("I am here.")
