用turtle画一幅海底世界

好的，让我来为您展示一下用turtle画一幅海底世界的代码：

import turtle

# 设置画笔和画布
pen = turtle.Turtle()
pen.speed(0)
pen.color('white')
pen.getscreen().bgcolor('blue')

# 画海底
pen.penup()
pen.goto(-300, -200)
pen.pendown()
pen.begin_fill()
pen.goto(300, -200)
pen.goto(300, 0)
pen.goto(-300, 0)
pen.goto(-300, -200)
pen.end_fill()

# 画海底草
pen.penup()
pen.goto(-250, -190)
pen.pendown()
pen.color('green')
pen.begin_fill()
for i in range(2):
    pen.forward(50)
    pen.right(90)
    pen.forward(100)
    pen.right(90)
pen.end_fill()

pen.penup()
pen.goto(-150, -190)
pen.pendown()
pen.color('green')
pen.begin_fill()
for i in range(2):
    pen.forward(70)
    pen.right(90)
    pen.forward(120)
    pen.right(90)
pen.end_fill()

pen.penup()
pen.goto(50, -190)
pen.pendown()
pen.color('green')
pen.begin_fill()
for i in range(2):
    pen.forward(60)
    pen.right(90)
    pen.forward(90)
    pen.right(90)
pen.end_fill()

# 画海底动物
pen.penup()
pen.goto(-200, -50)
pen.pendown()
pen.color('black')
pen.fillcolor('orange')
pen.begin_fill()
pen.circle(50)
pen.end_fill()

pen.penup()
pen.goto(100, -50)
pen.pendown()
pen.color('black')
pen.fillcolor('yellow')
pen.begin_fill()
pen.circle(50)
pen.end_fill()

# 画海星
pen.penup()
pen.goto(-100, -100)
pen.pendown()
pen.color('black')
pen.fillcolor('purple')
pen.begin_fill()
for i in range(5):
    pen.forward(50)
    pen.right(144)
pen.end_fill()

# 完成
turtle.done()

运行代码后，您就可以看到一幅色彩缤纷的海底世界啦！
