Python turtle艺术画赏析!

我一直在玩Python的turtle图形 – 这是一种有趣的学习方式,通过一些实验和思考,你可以想出画出各种有趣的图像。

示例1:

第一张图片的代码非常简单,绘制一束直线光线,使用嵌套循环使其变小,并且在每条射线的末尾涂鸦。

import turtle

import random

turtle.tracer(0, 0)

mi = turtle.Screen()

mi.colormode(255)

turtle.bgcolor(“black”)

alex = turtle.Turtle()

alex.speed(10)

alex.goto(0,0)

alex.pensize(0)

alex.ht()

for i in range(500):

alex.color(random.randrange(256),random.randrange(256),random.randrange(256))

alex.goto(round(random.gauss(0,150),0),round(random.gauss(0,150),0))

x = alex.xcor()

y = alex.ycor()

for j in range(25):

z = round(random.gauss(0,5), 0)

a = round(random.gauss(0,5), 0)

alex.color(random.randrange(256),random.randrange(256),random.randrange(256))

alex.pensize(0)

alex.goto(x + z, y + a)

alex.goto(z,a)

turtle.update()

mi.exitonclick()

直线脉冲效果图如下:

示例2:

画三组同心弯曲的光线,从黑暗中浮现,生成随机RGB值,sat range 0-1, val range = 0-1。

import random

import turtle

def colorGen(sat = 1, val = 1):

rand1 = round(random.randrange(256)*val)

rand2 = round(random.randrange(256)*val)

sat2 = round((1-sat)*255)

if rand1 >= rand2:

rand1 = round(255*val)

else:

rand2 = round(255*val)

color = [[sat2, rand1, rand2], [rand1, sat2, rand2], [sat2, rand2, rand1],

[rand1, rand2, sat2], [rand2, sat2, rand1], [rand2, rand1, sat2]]

return tuple(color[random.randrange(6)])

def timeTunnel(repeats = 1,linuxmi = 10, stepVar = 1):

for i in range(repeats):

alex.goto(0,0)

alex.seth(random.uniform(0,360)) # 设定标题

h1 = alex.heading() # 设定标题

alex.color(colorGen(val=0))

for j in range(10):

alex.down()

alex.forward(abs(round(random.gauss(10, stepVar),0)))

alex.seth(h1 + random.gauss(0,linuxmi))

x = alex.xcor()

y = alex.ycor()

alex.color(colorGen(val = j/10))

f2 = alex.heading()

for k in range(3):

alex.down()

alex.seth(f2 + random.gauss(0, linuxmi))

h3 = alex.heading()

for u2 in range(10):

alex.color(colorGen(val = u2/10))

alex.seth(h3 + random.gauss(0,linuxmi))

alex.forward(abs(round(random.gauss(10, stepVar), 0)))

m = alex.xcor()

n = alex.ycor()

h4 = alex.heading()

for l in range(2):

alex.color(colorGen())

alex.down()

alex.seth(abs(h4 + random.gauss(0,linuxmi)))

h5 = alex.heading()

for l2 in range(10):

alex.color(colorGen(val = l2/10))

alex.seth(h5 + random.gauss(0,linuxmi))

alex.forward(abs(round(random.gauss(10,stepVar),0)))

alex.up()

alex.goto(x, y)

alex.up()

turtle.tracer(0, 0)

wn = turtle.Screen()

wn.colormode(255)

turtle.bgcolor(“black”)

alex = turtle.Turtle()

alex.speed(10)

alex.pensize(0)

alex.ht()

timeTunnel(300)

turtle.update()

wn.exitonclick()

示例3:

代码如下:

from turtle import * # 导入模块turtle

speed(0) # 将绘图速度设置为0,这是最快的

pencolor(‘red’) # 设置钢笔/线条的颜色为红色

bgcolor(‘black’) # 设置背景/画布的颜色为黑色

x = 0 # 创建一个值为0的变量x

up() # 举起笔,这样就不会画线了

d()表示向前移动,bk() 示向后移动

rt()或lt()表示向右倾斜一定角度

rt(45)

fd(90)

rt(135)

down() # 放下笔,让乌龟画画

while x < 120: # 当x的值小于120时,

连续这样做:

fd(200)

rt(61)

fd(200)

rt(61)

fd(200)

rt(61)

fd(200)

rt(61)

fd(200)

rt(61)

fd(200)

rt(61)

rt(11.1111)

x = x+1 # #在x的值上加1,

所以每次循环后它都接近120

exitonclick() # 当您单击时,turtle退出。

效果如下:
