使用turtle库中的函数绘制“颜”这三个字

可以使用turtle库中的函数来绘制“颜”字，具体步骤如下：

1. 导入turtle库

import turtle

2. 创建画布和画笔

screen = turtle.Screen()
pen = turtle.Turtle()

3. 设置画笔的颜色和线条宽度

pen.pencolor("black")
pen.pensize(5)

4. 绘制“颜”字的第一个横线

pen.penup()
pen.goto(-100, 0)
pen.pendown()
pen.forward(200)

5. 绘制“颜”字的第一个竖线

pen.penup()
pen.goto(-100, 0)
pen.pendown()
pen.right(90)
pen.forward(100)

6. 绘制“颜”字的第二个竖线

pen.penup()
pen.goto(100, 0)
pen.pendown()
pen.left(180)
pen.forward(100)

7. 绘制“颜”字的第二个横线

pen.penup()
pen.goto(-100, -100)
pen.pendown()
pen.right(90)
pen.forward(200)

8. 绘制“颜”字的“口”字

pen.penup()
pen.goto(-70, -70)
pen.pendown()
pen.right(90)
pen.circle(30, 180)

9. 结束绘制

turtle.done()

完整代码如下：

import turtle

screen = turtle.Screen()
pen = turtle.Turtle()

pen.pencolor("black")
pen.pensize(5)

pen.penup()
pen.goto(-100, 0)
pen.pendown()
pen.forward(200)

pen.penup()
pen.goto(-100, 0)
pen.pendown()
pen.right(90)
pen.forward(100)

pen.penup()
pen.goto(100, 0)
pen.pendown()
pen.left(180)
pen.forward(100)

pen.penup()
pen.goto(-100, -100)
pen.pendown()
pen.right(90)
pen.forward(200)

pen.penup()
pen.goto(-70, -70)
pen.pendown()
pen.right(90)
pen.circle(30, 180)

turtle.done()
