Question

我正在尝试从导入的模块初始化sT。并得到错误：

sT = SierpinskiTriangle(self.dimensions, 50000, 0.5, vertices)
TypeError: SierpinskiTriangle() takes exactly 1 argument (4 given)

，我不太确定为什么或做错了什么。

sT = SierpinskiTriangle(self.dimensions, 50000, 0.5, vertices)

我已经从另一个文件导入了该文件：

 class Fractal(Canvas, Point):

    def __init__(self, dimensions, num_points, ratio, vertices):
        self.dimensions = dimensions
        self.num_points = num_points
        self.r = ratio
        self.vertices = vertices

    def frac_x(self, r):
        return int((self.dimensions["max_x"] - \
         self.dimensions["min_x"]) * r) + \
         self.dimensions["min_x"]

    def frac_y(self, r):
        return int((self.dimensions["max_y"] - \
         self.dimensions["min_y"]) * r) + \
         self.dimensions["min_y"]

def SierpinskiTriangle(Fractal):

    def __init__(self, dimensions, num_points, ratio, vertices):
        Fractal.__init__(self, dimensions, num_points, ratio, vertices)

编辑，这是Point类：

class Point(object):

    def __init__(self, x = 0.0, y = 0.0):
        self.x = float(x)
        self.y = float(y)

    @property
    def x(self):
        return self._x

    @x.setter
    def x(self, value):
        self._x = value

    @property
    def y(self):
        return self._y
    @y.setter
    def y(self, value):
        self._y = value

    def dist(self, secondPoint):
        #get the self x values from self.x and the values
        #of the seecond point from secondPoint.x
        #same with y
        dist = math.sqrt(((self.x - secondPoint.x)**2)+ ((self.y - secondPoint.y)**2))
        return dist

    def midpt(self, secondPoint):
        #same as the dist
        midpointx = (self.x + secondPoint.x)/2
        midpointy = (self.y + secondPoint.y)/2
        midpoint = Point(midpointx,midpointy)
        return midpoint

    def __str__(self):
        return "({},{})".format(self.x,self.y)

我希望这也有助于澄清问题。我没有Canvas类，因为它是Tkinter的一部分。

您为def使用了class而不是SierpinskiTriangle，这意味着它仅接受一个参数（Fractal）而不是将Fractal视为其超类。

将其更改为如下所示的类，它将需要4个参数。

class SierpinskiTriangle(Fractal):

    def __init__(self, dimensions, num_points, ratio, vertices):
        Fractal.__init__(self, dimensions, num_points, ratio, vertices)

SierpinskiTriangle（）恰好接受1个参数（给定4个）
