在Python中使用实际绘制的正方形实现形状类？

我有以下创建shape类的代码，我有两个问题需要解答： 1.运行以下代码时，输出为：

>>> 
100
100
None
>>> 

最后的“无”是什么，我怎样才能去掉这个输出？

2。理想情况下，我希望能够（在输出屏幕中）绘制一个正方形。我不希望使用pygame。我确实想知道是否有可能集成海龟来做这件事，但不知道如何开始？有没有关于使用海龟来实现这一点的方法的建议，或者任何其他天才的建议

from turtle import*
class Shape:
    #self is how we refer to things in the clas from within itself. .self is the first parameter in any function defined inside a class
    #to access functions and variables inside the class, their name must be preceded with self and a full-stop (e.g. self.variable_name)
    def __init__(self,x,y):
        self.x=x #the shape has the attribute x (width)
        self.y=y #the shape has the attribute y (height)

    description="The shape has not yet been brought into being"
    author="No one has yet claimed authorship of this shape"

    def area(self):
        return self.x*self.y
    def perimeter(self):
        return 2*self.x+2*self.y
    def describe(self,text):
        self.description =text
    def authorName(self,text):
        self.author=text
    def scaleSize(self,scale):
        self.x=self.x*scale
        self.y=self.y*scale
    def print(self):
        print(self.x)
        print(self.y)


square=Shape(100,100)
print(square.print())

我可以补充一点，在这方面也有类似的问题，但没有具体或有用的答案

更新：

我试过这样的东西，但没能奏效。我想我需要在构造函数中的某个地方初始化turtle-但是在哪里以及如何初始化

from turtle import*
class Shape:
    #self is how we refer to things in the clas from within itself. .self is the first parameter in any function defined inside a class
    #to access functions and variables inside the class, their name must be preceded with self and a full-stop (e.g. self.variable_name)
    def __init__(self,x,y):
        self.x=x #the shape has the attribute x (width)
        self.y=y #the shape has the attribute y (height)


    description="The shape has not yet been brought into being"
    author="No one has yet claimed authorship of this shape"

    def area(self):
        return self.x*self.y
    def perimeter(self):
        return 2*self.x+2*self.y
    def describe(self,text):
        self.description =text
    def authorName(self,text):
        self.author=text
    def scaleSize(self,scale):
        self.x=self.x*scale
        self.y=self.y*scale
    def print(self,shapename):
        print("This shape is a", shapename, "with dimensions:>",self.x,"by",self.y)
    def draw(self):
        turtle.forward(self.x)
        turtle.left(90)
        turtle.forward(se.f.x)
        turtle.left(90)
        turtle.forward(self.y)
        turtle.left(90)
        turtle.forward(self.y)
        turtle.left(90)



square=Shape(100,100)
square.print("square")
print("The perimeter is:",square.perimeter())
print(square.draw())

print（square.print（））由于函数不返回任何内容，所以该行在控制台上不生成任何内容。要删除它，只需删除外部打印（）并保留剩余的打印。i、 e.square.print（）

是的，这是可能的，我对你们的代码做了一些修改，现在它应该在屏幕上创建正方形了

---

print（square.print（））

由于函数不返回任何内容，所以这一行在控制台上不生成任何内容。要删除它，只需删除外部打印（）并保留剩余的打印。i、 e.

square.print（）

谢谢！对第二个问题有什么想法吗！我在上面：）我会随时更新谢谢！添加了一个更新。（draw的代码不正确）但这就是想法。我不知道从哪里可以让类识别海龟……警告，通过执行海龟导入中的

和
类形状：
您正在重新定义海龟自己的
形状
类！您可以通过在
类形状：
（重新）定义之前和之后打印
id（形状）
来确认这一点。您应该限制您的导入，
导入海龟
或
从海龟导入海龟，屏幕
，或者将您的
形状
类重命名为其他类。谢谢！海龟功能现在就在那里！！！！！！但是…它总是画一个正方形，并且不识别输入参数。我可以简单地将“正向”变量（例如50）更改为self.x和self.y吗etc@MissComputing我现在已经做了修改，所以现在它将使用用户输入，90是它改变方向的角度。我希望它对你有用：）太好了。非常感谢。作为最后一个请求，如果可能的话，请您对与添加turtle相关的代码进行注释。让用户了解它的实现。类的这一部分是怎样的…等等（例如canvas=Screen（）canvas.setup（800800）turtle\u obj=turtle（））
from turtle import*
class Shape:
    canvas = Screen() # creating object of screen class
    canvas.setup(800,800) # this will setup window on screen with dimension 800x800

    turtle_obj = Turtle() # creating object of turtle class which will be used to plot square on window

    #self is how we refer to things in the clas from within itself. .self is the first parameter in any function defined inside a class
    #to access functions and variables inside the class, their name must be preceded with self and a full-stop (e.g. self.variable_name)
    def __init__(self,x,y):
        self.x=x #the shape has the attribute x (width)
        self.y=y #the shape has the attribute y (height)

    description="The shape has not yet been brought into being"
    author="No one has yet claimed authorship of this shape"

    def area(self):
        return self.x*self.y
    def perimeter(self):
        return 2*self.x+2*self.y
    def describe(self,text):
        self.description =text
    def authorName(self,text):
        self.author=text
    def scaleSize(self,scale):
        self.x=self.x*scale
        self.y=self.y*scale

    def print(self):
        print self.x
        print self.y
        # now we are referring to class object turtle using self.turtle_obj and 
        # calling forward() function which will move plotting cursor in forward direction 
        # upto x pixels and left() will rotate direction by 90 degree 
        self.turtle_obj.forward(self.x)
        self.turtle_obj.left(90)
        self.turtle_obj.forward(self.y)
        self.turtle_obj.left(90)
        self.turtle_obj.forward(self.x)
        self.turtle_obj.left(90)
        self.turtle_obj.forward(self.y)
        self.turtle_obj.left(90)
