解释turtle中的shapesize
时间: 2024-06-03 21:08:57 浏览: 9
在turtle中,shapesize()函数用于设置海龟的形状大小。它有三个参数:stretched_wid, stretched_len和outline。stretched_wid和stretched_len可以是任何数字,它们分别控制海龟形状的宽度和长度。默认情况下,宽度和长度都是1。outline是一个可选参数,它可以设置海龟形状的轮廓线的宽度。默认情况下,轮廓线宽度为1。
使用shapesize()函数,可以改变海龟的形状大小,从而使其更适合特定的应用程序或绘图需求。例如,可以使用shapesize(2,2,3)来将海龟形状的宽度和长度都增加到原来的两倍,并将轮廓线宽度设置为3。这将使得海龟在绘制图形时更加明显和突出。

python中turtle.shapesize用法
`turtle.shapesize()` 是一个 Python Turtle Graphics 模块中的函数,用于设置画笔的大小和形状。它的用法如下:
```python
turtle.shapesize(stretch_wid=None, stretch_len=None, outline=None)
```
其中,`stretch_wid` 和 `stretch_len` 分别表示宽度和长度的缩放因子,如果不指定这两个参数,则表示不改变当前的大小。`outline` 是一个可选参数,它表示轮廓线的宽度。如果不指定,则使用当前的值。
例如,要将画笔的大小设置为 3,长度和宽度都缩小一半,可以使用以下代码:
```python
import turtle
turtle.shapesize(0.5, 0.5, 3)
```
turtle shapesize()
As an AI language model, I don't have the capability to display graphics or execute Python commands directly. However, I can provide you with some information about the `shapesize()` method in Python's turtle module.
`shapesize()` is a turtle method that sets the size of the turtle shape. It takes three arguments: `stretch_wid`, `stretch_len`, and `outline`.
The `stretch_wid` argument specifies the stretch factor for the turtle shape's width. The default value is 1, which means no stretching. A value greater than 1 stretches the shape horizontally, and a value less than 1 compresses it.
The `stretch_len` argument specifies the stretch factor for the turtle shape's length. The default value is 1, which means no stretching. A value greater than 1 stretches the shape vertically, and a value less than 1 compresses it.
The `outline` argument specifies the width of the turtle shape's outline. The default value is 1.
Here's an example of using `shapesize()` to set the size of a turtle shape:
```
import turtle
t = turtle.Turtle()
t.shape("turtle")
t.shapesize(2, 2, 3)
```
This code creates a turtle object, sets its shape to "turtle", and uses `shapesize()` to stretch the width and length of the turtle shape by a factor of 2 and set the outline width to 3.
