Python中的turtle.get_shapepoly()函数

turtle模块以面向对象和面向过程的方式提供Turtle图形基元。因为它使用 Tkinter 作为底层图形，它需要安装一个支持 Tk 的 Python 版本。

turtle.get_shapepoly()

该方法用于返回当前形状的多边形，作为一个坐标对的元组。它不需要任何参数。

语法:

turtle.get_shapepoly()

下面是上述方法的实现和一些例子。

例子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))

例子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’]
