python turtle创意作品

以下是一些Python Turtle的创意作品：

1. 绘制彩色螺旋线：使用Python Turtle绘制不同颜色的线条，创建一个漂亮的彩色螺旋图案。

import turtle
import random

turtle.speed(0)
turtle.bgcolor('black')

colors = ['red', 'orange', 'yellow', 'green', 'blue', 'purple']

for i in range(150):
    turtle.color(random.choice(colors))
    turtle.pensize(i/10 + 1)
    turtle.forward(i)
    turtle.left(59)

2. 绘制海龟赛跑游戏：使用Python Turtle创建一个简单的海龟赛跑游戏，让玩家控制一个小海龟，尽可能快地穿过障碍物。

import turtle
import random

# Set up the screen
screen = turtle.Screen()
screen.setup(500, 500)
screen.title("Turtle Race")

# Create the turtles
turtles = []
colors = ['red', 'orange', 'yellow', 'green', 'blue', 'purple']
for i in range(6):
    turtle = turtle.Turtle()
    turtle.shape('turtle')
    turtle.color(colors[i])
    turtle.penup()
    turtle.goto(-230, 200 - i*50)
    turtles.append(turtle)

# Create the finish line
finish = turtle.Turtle()
finish.penup()
finish.goto(230, 200)
finish.pendown()
finish.goto(230, -200)

# Start the race
while True:
    for turtle in turtles:
        turtle.forward(random.randint(1, 5))
        if turtle.xcor() >= 230:
            winner = turtle.color()[0]
            print("The winner is", winner)
            turtle.goto(-100, 0)
            turtle.write("Winner!", font=("Arial", 16, "bold"))
            break

3. 绘制谢尔宾斯基三角形：使用Python Turtle绘制一个谢尔宾斯基三角形，这是一个典型的分形图形。

import turtle

def draw_triangle(points, color, turtle):
    turtle.fillcolor(color)
    turtle.up()
    turtle.goto(points[0][0], points[0][1])
    turtle.down()
    turtle.begin_fill()
    turtle.goto(points[1][0], points[1][1])
    turtle.goto(points[2][0], points[2][1])
    turtle.goto(points[0][0], points[0][1])
    turtle.end_fill()

def get_mid(p1, p2):
    return ((p1[0]+p2[0])/2, (p1[1]+p2[1])/2)

def sierpinski(points, degree, turtle):
    colormap = ['blue', 'red', 'green', 'white', 'yellow',
                'violet', 'orange']
    draw_triangle(points, colormap[degree], turtle)
    if degree > 0:
        sierpinski([points[0],
                    get_mid(points[0], points[1]),
                    get_mid(points[0], points[2])],
                   degree-1, turtle)
        sierpinski([points[1],
                    get_mid(points[0], points[1]),
                    get_mid(points[1], points[2])],
                   degree-1, turtle)
        sierpinski([points[2],
                    get_mid(points[2], points[1]),
                    get_mid(points[0], points[2])],
                   degree-1, turtle)

turtle.setup(500, 500)
turtle.title("Sierpinski Triangle")

my_turtle = turtle.Turtle()
my_turtle.speed(0)
my_points = [[-200, -100], [0, 200], [200, -100]]
sierpinski(my_points, 3, my_turtle)

turtle.done()
