python编程代码画哆啦a梦

来源 :华课网校 2024-08-03 20:34:08

Python是一种高级编程语言,具有简单、易学、易读等优点。它的应用领域非常广泛,其中包括图形绘制。本文将介绍如何用Python编写代码绘制哆啦A梦。

首先,我们需要导入Python中的绘图库turtle。通过它,我们可以控制海龟在屏幕上绘制图形。代码如下:

```Python

import turtle

```

接下来,我们需要定义一些常量,如哆啦A梦头部的半径、身体的长度、手臂和脚的长度等。代码如下:

```Python

HEAD_RADIUS = 80

BODY_LENGTH = 180

ARM_LENGTH = 80

LEG_LENGTH = 100

```

然后,我们可以开始绘制哆啦A梦的头部。我们使用turtle.circle()函数来绘制一个圆形。代码如下:

```Python

turtle.penup()

turtle.goto(0, -HEAD_RADIUS)

turtle.pendown()

turtle.circle(HEAD_RADIUS)

```

接下来,我们绘制哆啦A梦的身体。使用turtle.forward()函数来绘制直线,turtle.left()和turtle.right()函数来控制海龟的转向。代码如下:

```Python

turtle.left(90)

turtle.forward(BODY_LENGTH)

turtle.left(90)

turtle.forward(HEAD_RADIUS * 2)

turtle.left(90)

turtle.forward(BODY_LENGTH)

```

接下来,我们绘制哆啦A梦的手臂。使用turtle.forward()和turtle.right()函数来控制海龟的移动和转向。代码如下:

```Python

turtle.right(90)

turtle.forward(ARM_LENGTH)

turtle.right(180)

turtle.forward(ARM_LENGTH)

turtle.right(180)

turtle.forward(ARM_LENGTH)

turtle.right(90)

```

接下来,我们绘制哆啦A梦的脚。代码如下:

```Python

turtle.left(90)

turtle.forward(LEG_LENGTH)

turtle.left(180)

turtle.forward(LEG_LENGTH)

turtle.right(90)

turtle.forward(LEG_LENGTH)

```

最后,我们可以在哆啦A梦的头部上绘制一个小圆和两条弯曲的线,来表示它的眼睛和嘴巴。代码如下:

```Python

turtle.penup()

turtle.goto(-HEAD_RADIUS / 2, HEAD_RADIUS / 2)

turtle.pendown()

turtle.circle(HEAD_RADIUS / 4)

turtle.penup()

turtle.goto(-HEAD_RADIUS / 2, HEAD_RADIUS / 4)

turtle.pendown()

turtle.right(30)

turtle.forward(HEAD_RADIUS / 2)

turtle.right(120)

turtle.forward(HEAD_RADIUS / 2)

```

最后,我们可以调用turtle.done()函数来保持窗口打开状态,以便我们可以欣赏我们的作品。完整的代码如下:

```Python

import turtle

HEAD_RADIUS = 80

BODY_LENGTH = 180

ARM_LENGTH = 80

LEG_LENGTH = 100

turtle.penup()

turtle.goto(0, -HEAD_RADIUS)

turtle.pendown()

turtle.circle(HEAD_RADIUS)

turtle.left(90)

turtle.forward(BODY_LENGTH)

turtle.left(90)

turtle.forward(HEAD_RADIUS * 2)

turtle.left(90)

turtle.forward(BODY_LENGTH)

turtle.right(90)

turtle.forward(ARM_LENGTH)

turtle.right(180)

turtle.forward(ARM_LENGTH)

turtle.right(180)

turtle.forward(ARM_LENGTH)

turtle.right(90)

turtle.left(90)

turtle.forward(LEG_LENGTH)

turtle.left(180)

turtle.forward(LEG_LENGTH)

turtle.right(90)

turtle.forward(LEG_LENGTH)

turtle.penup()

turtle.goto(-HEAD_RADIUS / 2, HEAD_RADIUS / 2)

turtle.pendown()

turtle.circle(HEAD_RADIUS / 4)

turtle.penup()

turtle.goto(-HEAD_RADIUS / 2, HEAD_RADIUS / 4)

turtle.pendown()

turtle.right(30)

turtle.forward(HEAD_RADIUS / 2)

turtle.right(120)

turtle.forward(HEAD_RADIUS / 2)

turtle.done()

```

运行代码,我们可以在窗口中看到一个可爱的哆啦A梦!
