import turtle
# circle有三个参数，1.半径每像数，2.steps=X 分部，3.extent=X 度数
#画一个半径为十的圆
#turtle.circle(10)
#画一个正八边形
#turtle.circle(30,steps=8)
#画一个120的弧
#turtle.circle(50,extent=120)

#1.同切圆
#for i in range(10):
# turtle.circle(100-(i*10))

#2.同心圆
#for i in range(10):
# turtle.up()
# turtle.goto(0,i*10)
# turtle.down()
# turtle.circle(100-(i*10))

#3.五角星
#for i in range(5):
# turtle.forward(100)
# turtle.right(144)

#4.填充黄色的五角星
#turtle.color(‘yellow‘)
#turtle.fillcolor(‘yellow‘)
#turtle.begin_fill()
#for i in range(5):
# turtle.forward(100)
# turtle.right(144)
#turtle.end_fill()

#在红底下的五颗五角星
turtle.color(‘yellow‘)
turtle.fillcolor(‘yellow‘)
turtle.bgcolor(‘red‘)
turtle.up()
turtle.goto(-300,300)
turtle.down()

for j in range(6):
　　turtle.begin_fill()
　　for i in range(5):
　　　　turtle.forward(100)
　　　　turtle.right(144)
　　　turtle.end_fill()
　　turtle.up()
　　turtle.goto(-300+(j*100),300-(j*80))
　　turtle.down()
