python turtle工具绘制四叶草的实例分享
本篇文章介绍了python使用turtle库绘制四叶草的方法,代码很简单,希望对学习python的朋友有帮助。
import turtle
import time
turtle.setup(650.,350,200,200)
turtle.pendown()
turtle.pensize(10)
turtle.pencolor('green')
#四叶草
def draw_clover(radius,rotate): #参数radius控制叶子的大小,rotate控制叶子的旋转
for i in range(4):
direction = i*90
turtle.seth(60+direction+rotate) #控制叶子根部的角度为60度
# turtle.fd(2*radius*pow(2,1/2)) #控制叶子根部的角度为90度
turtle.fd(4*radius)
for j in range(2):
turtle.seth(90+direction+rotate)
turtle.circle(radius,180)
turtle.seth(-60+direction+rotate)
turtle.fd(4*radius)
turtle.seth(-90)
turtle.fd(6*radius)
draw_clover(30,45)
time.sleep(5)
内容扩展
import turtle
def draw_shapes():
window = turtle.Screen()
window.bgcolor("red")
flower = turtle.Turtle()
flower.speed(10)
flower.shape("arrow")
flower.right(45)
for i in range(1,37):
for j in range(1,5):
draw_circle(flower,i,"green")
flower.left(90)
flower.right(45)
flower.color("green")
flower.forward(500)
window.exitonclick()
def draw_circle(circle,radius,color):
circle.color(color)
circle.circle(radius)
draw_shapes()
