Question

每次单击“agregar”按钮时，我都试图将输入数字附加到我的数组数据中，但是它似乎只附加了我刚刚插入的值，而完全忘记了之前的附加值。我没有收到任何错误消息。此外，当我单击“iniciar”时，它应该使用数据中的值绘制椭圆，但出现错误

<块引用>

TypeError: Iniciar() 缺少 1 个必需的位置参数：'data'

我不确定我做错了什么，如果有人能提供帮助，我将不胜感激。

Answer 1

您在此处定义 Iniciar：

def Iniciar(data):
    print("Se selecciono: " + algoritmo.get())
 
    dibujar(a)

但是当您在下面调用它时，您并没有向它传递 data 参数

botonStart = Button(box, text = 'Iniciar', command = Iniciar, bg = 'lime green')

类型错误：Iniciar() 缺少 1 个必需的位置参数：“数据”并且追加失败
