1)画五角星
import turtle
turtle.color(\'yellow\')
turtle.fillcolor(\'yellow\')
turtle.begin_fill()
for i in range(5):
turtle.forward(80)
turtle.left(144)
turtle.end_fill()
2)画同心圆
import turtle
for i in range(4):
turtle.circle((i+1)*10)
turtle.up()
turtle.goto(0,-(i+1)*10)
turtle.down()
3)画太阳花
import turtle
turtle.fillcolor("blue")
turtle.begin_fill()
while True:
turtle.forward(200)
turtle.left(135)
if(abs(turtle.pos()))<1:
break
turtle.end_fill()
4)画五个角星
import turtle
turtle.bgcolor(\'red\')
turtle.color(\'yellow\')
turtle.fillcolor(\'yellow\')
def mygoto(x,y):
turtle.up()
turtle.goto(x,y)
turtle.down()
mygoto(-250,75)
turtle.begin_fill()
for i in range(5):
turtle.forward(100)
turtle.left(144)
turtle.end_fill()
mygoto(-130,150)
turtle.begin_fill()
for i in range(5):
turtle.forward(30)
turtle.left(144)
turtle.end_fill()
mygoto(-70,110)
turtle.begin_fill()
for i in range(5):
turtle.forward(30)
turtle.left(144)
turtle.end_fill()
mygoto(-75,35)
turtle.begin_fill()
for i in range(5):
turtle.forward(30)
turtle.left(144)
turtle.end_fill()
mygoto(-130,-25)
turtle.begin_fill()
for i in range(5):
turtle.forward(30)
turtle.left(144)
turtle.end_fill()
