Python turtle.get_shapepoly()用法及代码示例

turtle 模块以面向对象和面向过程的方式提供 turtle 图形基元。由于它使用Tkinter作为基础图形，因此需要安装有Tk支持的Python版本。

turtle .get_shapepoly()

此方法用于将当前形状多边形作为坐标对元组返回。它不需要任何参数。

用法:

turtle.get_shapepoly()

下面是上述方法的实现和一些示例：

范例1：

# import package 
import turtle 
  
# get default shape 
print(turtle.shape()) 
  
# get default shapeploy 
print(turtle.get_shapepoly()) 
  
# set some size 
turtle.turtlesize(5, 5, 2) 
  
# get default shapeploy 
print(turtle.get_shapepoly())

输出：

classic
((0, 0), (-5, -9), (0, -7), (5, -9))
((0.0, 0.0), (-25.0, -45.0), (0.0, -35.0), (25.0, -45.0))

范例2：

# import package 
import turtle 
  
# get all shapes 
shp=turtle.getshapes() 
print(shp) 
  
# loop for getting shapepoly 
# of all the shapes 
for i in range(len(shp)):
    turtle.shape(shp[i]) 
    print(turtle.get_shapepoly())

输出：

[‘arrow’, ‘blank’, ‘circle’, ‘classic’, ‘square’, ‘triangle’, ‘turtle’]
