I keep on getting an error saying Player object has no attribute go_up when i have clearly defined it in the player class.

Error message: File "C:\Users\mctri\OneDrive\Desktop\Maze
game\src\main.py", line 134, in <module>
        turtle.onkey(player.go_up,"Up")

go_up is not actually in the Player class, due to its indentation:

class Player(turtle.Turtle):
    def __init__(self):
        ...

#Player movement
def go_up(self):
    ...

It has to be the same indentation level as __init__ in order to be considered a part of the Player class:

class Player(turtle.Turtle):
    def __init__(self):
        ...

    #Player movement
    def go_up(self):
        ...

Same goes for go_down, go_right, etc.

Indentation is what is used to group functions that are bound to a class, otherwise known as member methods. Just remember they should be siblings of your __init__() class constructor.

class Player(turtle.Turtle):
    def __init__(self):
        turtle.Turtle.__init__(self)
        self.shape("circle")
        self.color("red")
        self.penup()
        self.speed(0)
        self.gold = 0
    
    #Player movement
    def go_up(self):
        move_to_x = player.xcor()
        move_to_y = player.ycor() + 24
        if (move_to_x, move_to_y) not in walls:
            self.goto(move_to_x, move_to_y)
    
    def go_down(self):
        move_to_x = player.xcor()
        move_to_y = player.ycor() - 24
        if (move_to_x, move_to_y) not in walls:
            self.goto(move_to_x, move_to_y)
