1.用循环画五角星
import turtle
turtle.setup(600,400,0,0)
turtle.color("yellow")
turtle.bgcolor('red')
turtle.fillcolor("yellow")
turtle.up()
turtle.goto(-250,75)
turtle.down()
turtle.begin_fill()
for i in range(5):
turtle.forward(100)
turtle.right(144)
turtle.end_fill()
2.用循环画同心圆
from turtle import*
for i in range(5):
up()
goto(0,-20*(i))
down()
circle(20*i)
3.用while循环画太阳花
from turtle import*
color('red','blue')
begin_fill()
while True:
forward(200)
left(170)
if (abs(pos()))<1:
break
end_fill()
done()
import turtle
turtle.setup(600,400,0,0)
turtle.color("yellow")
turtle.bgcolor('red')
turtle.fillcolor("yellow")
turtle.up()
turtle.goto(-250,75)
turtle.down()
turtle.begin_fill()
for i in range(5):
turtle.forward(100)
turtle.right(144)
turtle.end_fill()
turtle.up()
turtle.goto(-100,-10)
turtle.down()
turtle.begin_fill()
for i in range(5):
turtle.forward(50)
turtle.left(144)
turtle.end_fill()
turtle.up()
turtle.goto(-50,50)
turtle.down()
turtle.begin_fill()
for i in range(5):
turtle.forward(50)
turtle.right(144)
turtle.end_fill()
turtle.up()
turtle.goto(-50,120)
turtle.down()
turtle.begin_fill()
for i in range(5):
turtle.forward(50)
turtle.right(144)
turtle.end_fill()
turtle.up()
turtle.goto(-100,160)
turtle.down()
turtle.begin_fill()
for i in range(5):
turtle.forward(50)
turtle.left(144)
turtle.end_fill()
turtle.color("red")
5.用函数定义画钻石花瓣的太阳花
import turtle
def draw_diamond(brad):
brad.forward(100)
brad.right(45)
brad.forward(100)
brad.right(135)
def draw_art():
window=turtle.Screen()
window.bgcolor("purple")
brad=turtle.Turtle()
brad.shape("turtle")
brad.color("orange")
brad.speed("fastest")
for i in range(0,36):
draw_diamond(brad)
draw_diamond(brad)
brad.left(10)
brad.right(90)
brad.forward(155)
brad.color('green')
brad.forward(145)
window.exitonclick()
draw_art()
