turtle库基础练习
1 画一组同切圆
>>> import turtle >>> turtle.circle(10) >>> turtle.circle(30) >>> turtle.circle(50) >>> turtle.circle(70) >>>
2、画一组同心圆
import turtle >>> turtle.up() >>> turtle.goto(0,-20) >>> turtle.down() >>> turtle.circle(20) >>> turtle.up() >>> turtle.goto(0,-30) >>> turtle.down() >>> turtle.circle(30) >>> turtle.up() >>> turtle.goto(0,-40) >>> turtle.down() >>> turtle.circle(40)
>>>turtle.done()
3、画一个五角星
>>> turtle.speed(1) >>> tuetle.forward(100) >>> turtle.forward(100) >>> turtle.right(144) >>> turtle.forward(100) >>> turtle.right(144) >>> turtle.forward(100) >>> turtle.right(144) >>> turtle.forward(100) >>> turtle.right(144) >>> turtle.forward(100)
4、画一个黄色实心五角星
turtle.color("yellow") >>> turtle.begin_fill() >>> turtle.forward(100) >>> turtle.right(144) >>> turtle.forward(100) >>> turtle.right(144) >>> turtle.forward(100) >>> turtle.right(144) >>> turtle.forward(100) >>> turtle.right(144) >>> turtle.forward(100) >>> turtle.end_fill() >>> turtle.hideturtle() >>> turtle.done()
5、画左上角的五颗五角星
import turtle turtle.bgcolor('red') turtle.up() turtle.goto(-350,180) turtle.down() turtle.pencolor('yellow') turtle.fillcolor('yellow') turtle.begin_fill() turtle.forward(100) turtle.right(144) turtle.forward(100) turtle.right(144) turtle.forward(100) turtle.right(144) turtle.forward(100) turtle.right(144) turtle.forward(100) turtle.end_fill() turtle.hideturtle() turtle.up() turtle.goto(-150,250) turtle.down() turtle.pencolor('yellow') turtle.fillcolor('yellow') turtle.begin_fill() turtle.left(50) turtle.forward(40) turtle.right(144) turtle.forward(40) turtle.right(144) turtle.forward(40) turtle.right(144) turtle.forward(40) turtle.right(144) turtle.forward(40) turtle.end_fill() turtle.hideturtle() turtle.up() turtle.goto(-130,200) turtle.down() turtle.pencolor('yellow') turtle.fillcolor('yellow') turtle.begin_fill() turtle.left(50) turtle.forward(40) turtle.right(144) turtle.forward(40) turtle.right(144) turtle.forward(40) turtle.right(144) turtle.forward(40) turtle.right(144) turtle.forward(40) turtle.end_fill() turtle.hideturtle() turtle.up() turtle.goto(-70,130) turtle.down() turtle.pencolor('yellow') turtle.fillcolor('yellow') turtle.begin_fill() turtle.left(45) turtle.forward(40) turtle.right(144) turtle.forward(40) turtle.right(144) turtle.forward(40) turtle.right(144) turtle.forward(40) turtle.right(144) turtle.forward(40) turtle.end_fill() turtle.hideturtle() turtle.up() turtle.goto(-160,50) turtle.down() turtle.pencolor('yellow') turtle.fillcolor('yellow') turtle.begin_fill() turtle.left(50) turtle.forward(40) turtle.right(144) turtle.forward(40) turtle.right(144) turtle.forward(40) turtle.right(144) turtle.forward(40) turtle.right(144) turtle.forward(40) turtle.end_fill() turtle.hideturtle() turtle.done()
