实验八 Python库应用编程与体验

实验1,2

from turtle import*
from random import random, randint
def moveto(x,y):
    penup()
    goto(x,y)
    pendown()

setup(800,600)
speed(100)

radius=180
for i in range(9):
    moveto(0,-radius)

    rgb=tuple(random() for i in range(3))
    color(rgb)
    begin_fill()
    circle(radius)
    end_fill()
    radius-=20
hideturtle()
done()

实验3

from turtle import*

def square(size=50,rgb='pink'):
  
    pencolor(rgb)
    for i in range(4):
        fd(size)
        lt(90)

    setup(800,600)
    speed(10)
    n=10
    for i in range(n):
        square(80,'orange')
        lt(360/n)
        hideturtle()

    done()
