Python中的 turtle.turtlesize()函数
turtle 模块以面向对象和面向过程的方式提供海龟图形原语。因为它使用 Tkinter 作为底层图形,所以它需要安装一个支持 Tk 的Python版本。
乌龟.turtlesize()
此函数用于返回或设置笔的属性 x 或 y 拉伸因子和轮廓。
句法 :
turtle.turtlesize(stretch_wid=None, stretch_len=None, outline=None)
参数:
Arguments | Value Type | Description |
stretch_wid | positive number | stretchfactor perpendicular to orientation |
stretch_len | positive number | stretchfactor in direction of turtles orientation |
outline | positive number | determines the width of the shapes’s outline |
以下是上述方法的实现以及一些示例:
示例 1:
Python3
# import package
import turtle
# set turtle
turtle.speed(1)
turtle.shape("turtle")
turtle.fillcolor("blue")
# loop for motion
for i in range(4):
# set turtle width
turtle.turtlesize(stretch_wid=(i+1)*0.5)
turtle.forward(100)
turtle.right(90)
Python3
# import package
import turtle
# set turtle
turtle.speed(1)
turtle.shape("turtle")
turtle.fillcolor("blue")
# loop for motion
for i in range(4):
# set turtle length
turtle.turtlesize(stretch_len=(i+1)*0.5)
turtle.forward(100)
turtle.right(90)
Python3
# import package
import turtle
# set turtle
turtle.speed(1)
turtle.shape("turtle")
turtle.fillcolor("blue")
# loop for motion
for i in range(4):
# set turtle outline
turtle.turtlesize(outline=i+1)
turtle.forward(100)
turtle.right(90)
Python3
# import package
import turtle
# set turtle
turtle.speed(1)
turtle.shape("turtle")
turtle.fillcolor("blue")
# loop for motion
for i in range(4):
# set turtlesize properties all together
turtle.turtlesize(stretch_wid=(i+1)*0.5,
stretch_len=(i+1)*0.5,
outline=(i+1)
)
turtle.forward(100)
turtle.right(90)
输出 :
