我不知道可能是什么问题。
答案 0 :(得分：1)
通常，当您创建类draw的实例时，会自动为您调用初始化例程draw.__init__，并隐式添加self参数，因此您不会; t明确指定它。这是正常情况：
d = draw( canvas, 20, 40, ... )
......事实上，这似乎就是你所假设的。您的错误是明确地调用构造函数draw.__init__ 。当您想要这样做时， 某些情况，例如在初始化子类的实例时。但这些往往是更复杂/专业的案例。 如果你这样做，那么你需要在你的通话中明确提供self，而你却没有这样做。所以发生的事情是你的canvas值被分配到self，20被分配到canvas（因此错误），依此类推。
d = draw( canvas, 20, 40, ... ) # you mean this
draw.__init__( d, canvas, 20, 40, ... ) # not this (which is correct if you're calling the draw initializer on some pre-existing object d)
我还注意到您已经定义了一个想要使用axies值的方法canvas。正如它的编写，该代码将寻找一个名为canvas的全局变量。设计事物的一种更安全的方法是使该变量成为draw实例的属性。这意味着在self.canvas = canvas的主体中分配__init__，然后在其他方法中将其称为self.canvas而不仅仅是canvas（忘记最后一部分是一个非常常见的错误我）。
