Question

我正在制作一个使用codeskulptor创建图形的python程序，我想出了这个错误，我不知道它有什么问题，我该如何解决？代码：

    pointx = 0
    pointy = 0
    prepointx = 0
    prepointy = 0
    positionx = []
    positiony = []
    def draw_handler(canvas):
        global pointx, pointy 
    for v in range(len(values)):
        if v != 0:
            prepointx = pointx
            prepointy = pointy
        pointx = v * 6 
        pointy = values[v] - 45 * 2
        canvas.draw_point((pointx, pointy), 'red')
        if v != 0: //Syntax error:bad token '' 
            canvas.draw_line((prepointx, prepointy), (pointx, pointy), 3, 'red')  
        frame = simplegui.create_frame('Data', 425, 300)
        frame.set_draw_handler(draw_handler)

        frame.start

Answer 1

Your code is wronged indented. Also values is not defined. But the real problem is probably frame.start. To call the start method you must do frame.start().

I made the corrections, see: http://www.codeskulptor.org/#user40_zJYfuypQ0CWRHRA.py
