基于NSEW路径的无人机网格路线绘制与笛卡尔坐标输出异常

我需要根据TXT文件中的NSEW方向指令，在网格中绘制无人机飞行路线，并输出无人机位置的笛卡尔坐标。当前运行代码时，要么网格显示正确但坐标输出错误，要么两者均出错。目前只能通过维护两个drone_pos变量临时解决问题，这显然冗余。我怀疑问题出在索引与坐标的转换逻辑上：

def file2list(file):
    """
    Helper function that converts a file to a list
    """
    with open(file) as f:
        lines = [word for line in f for word in line.split()]
    
    return lines 

def cart2index(x, y, height):
    idxX = x - 1
    idxY = height - y

    return [idxY, idxX]

def cart2indexreverse(x, y, height):
    idxX = x - 1
    idxY = height - y

    return [idxX, idxY]


def index2cart(x, y, height):
    Xcoord = x + 1
    Ycoord = height - y

    return [Xcoord, Ycoord]
...

    for row in grid:
        print(str(row))
