Question

I have this code within a classless function:

        while room.getNumCleanedTiles() < min_coverage * room.getNumTiles():
            for index in range(0, len(roboList)):
                room.cleanTileAtPosition(positionList[index])
                roboList[index].updatePositionAndClean()
                positionList[index] = roboList[index].getRobotPosition
                count += 1

• positionList is a list of positions of the class Position.
• The position class has two methods, getX and getY.
• The room variable is a room of class Rectangular Room, which has a method known as cleanTileAtPosition, which takes a position as its argument and does some operations using the getX() and getY() methods.

The code is too large to reasonably attach here in its entirety, but the problem seems to be localized to the methods and classes I have described. I am getting an error that states:

"AttributeError: 'function' object has no attribute 'getX.'" 

However, through print statements it is clear that positionList[index] is indeed a position of class Position; that room is a RectangularRoom; and that getX() and getY() work on the position when they are called independently of the cleanTileAtPosition.

Is there anything about this code that seems like it would raise the error I am getting?

Answer 1

add () after getRobotPosition.
