Python海龟画潜水艇代码

Python海龟画潜水艇代码是一种基于Python中turtle库的绘图程序，通过turtle库提供的函数和方法来绘制出一个潜水艇的图形。以下是Python海龟画潜水艇代码的实现步骤：

1. 导入turtle库

import turtle

2. 创建画布和画笔

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

3. 绘制潜水艇的外形

# 潜水艇的船体
pen.pensize(4)
pen.penup()
pen.goto(-150,0)
pen.pendown()
pen.color('gray')
pen.circle(50,180)
pen.forward(300)
pen.circle(50,180)

# 潜水艇的舷窗
pen.penup()
pen.goto(-60,0)
pen.pendown()
pen.color('black')
pen.circle(20)
pen.penup()
pen.goto(60,0)
pen.pendown()
pen.color('black')
pen.circle(20)

# 潜水艇的螺旋桨
pen.penup()
pen.goto(-120,-50)
pen.pendown()
pen.color('black')
pen.begin_fill()
for i in range(3):
    pen.forward(240)
    pen.left(120)
pen.end_fill()

# 潜水艇的尾部
pen.penup()
pen.goto(-150,0)
pen.pendown()
pen.color('gray')
pen.begin_fill()
for i in range(2):
    pen.forward(30)
    pen.right(90)
    pen.forward(100)
    pen.right(90)
pen.end_fill()

4. 完成绘图并显示结果

window.exitonclick()
