turtle画图代码大全

以下是turtle模块的常用绘图代码：

1. 画一个正方形：

import turtle

pen = turtle.Turtle()

for i in range(4):
    pen.forward(100)
    pen.right(90)

turtle.done()

2. 画一个圆形：

import turtle

pen = turtle.Turtle()

pen.circle(50)

turtle.done()

3. 画一个三角形：

import turtle

pen = turtle.Turtle()

for i in range(3):
    pen.forward(100)
    pen.left(120)

turtle.done()

4. 画一个五角星：

import turtle

pen = turtle.Turtle()

for i in range(5):
    pen.forward(100)
    pen.right(144)

turtle.done()

5. 画一个正多边形：

import turtle

pen = turtle.Turtle()

num_sides = 6
side_length = 70
angle = 360.0 / num_sides

for i in range(num_sides):
    pen.forward(side_length)
    pen.right(angle)

turtle.done()

6. 画一个螺旋线：

import turtle

pen = turtle.Turtle()

for i in range(100):
    pen.forward(i)
    pen.right(20)

turtle.done()

7. 画一个彩色螺旋线：

import turtle
import random

pen = turtle.Turtle()

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

for i in range(100):
    pen.color(random.choice(colors))
    pen.forward(i)
    pen.right(20)

turtle.done()
