第二章turtle库语法元素分析

任务

1编程实现以下效果：将代码及结果截图上传

import turtle
turtle.setup(500,500,100,100)
turtle.pensize(5)
turtle.goto(100,100)
turtle.goto(100,-100)
turtle.goto(-100,-100)
turtle.goto(-100,100)
turtle.goto(0,0)
turtle.done()

2实现代码及效果

import turtle
turtle.setup(500,500,100,100)
turtle.pensize(5)
turtle.circle(50,360)
turtle.fd(100)
turtle.circle(50,360)
turtle.done()

3实现代码及效果

import turtle
turtle.setup(500,500,100,100)
turtle.pensize(5)
turtle.seth(45)
turtle.fd(150)
turtle.seth(-90)
turtle.fd(300)
turtle.seth(45)
turtle.fd(150)
turtle.done()

4实现代码及效果

import turtle
turtle.setup(500,500,100,100)
turtle.pensize(2)
turtle.pencolor("blue")
for i in range(30):
    if(i<15):
        turtle.fd(10+i*10)
        turtle.seth(90*i)
    else:
        turtle.pensize(5)
        turtle.pencolor("red")
        turtle.fd(10 + i * 10)
        turtle.seth(90 * i)
turtle.done()

5实现代码及效果

import turtle
turtle.setup(500,500,100,100)
turtle.pensize(4)
turtle.pencolor("yellow")
turtle.fillcolor("red")
turtle.begin_fill()
for i in range(5):
    turtle.seth(i*(-144))
    turtle.fd(150)
turtle.end_fill()

turtle.done()

6实现彩色蟒蛇

import turtle
turtle.setup(500,500,100,100)
turtle.penup()
turtle.fd(-200)
turtle.pensize(15)
turtle.pencolor("yellow")
turtle.pendown()
turtle.seth(-40)
turtle.pencolor("green")
turtle.circle(40,80)
turtle.circle(-40,80)
turtle.pencolor("blue")
turtle.circle(40,80)
turtle.circle(-40,80)
turtle.pencolor("yellow")
turtle.circle(40,80)
turtle.circle(-40,80)
turtle.pencolor("red")
turtle.circle(40,80)
turtle.circle(-40,80)
turtle.done()
