[Python] Enums in Python: How to enforce in method arguments

I want to use enums in Python like the following Java code below:

class Direction {
public enum Direction {LEFT, RIGHT, UP, DOWN}

public void navigate(Direction direction)
switch(direction){
case Direction.LEFT:
System.out.print("left");
break;
case Direction.RIGHT:
System.out.print("right");
break;
case Direction.UP:
System.out.print("up");
break;
case Direction.DOWN:
System.out.print("down");
break;
}
}
