实验八

from turtle import *
def square(size=50, rgb='pink'):
    '''绘制正方形
    参数size指定边长
    参数rgb指定画笔颜色
    如果没有给参数,采用默认值
    '''
    pencolor('purple')
    for i in range(4):
        fd(size)
        left(90)
def main():
    setup(800, 600)
    speed(0)
    n = 10
    for i in range(n):
        square(80)
        left(360/n)
    hideturtle()
    done()
if __name__ == '__main__':
    main()

 

 任务四

from turtle import *
setup(800, 600)
pencolor('black')
speed(0)
n = 10
for i in range(n):
    # 绘制一片花瓣
    for j in range(2):
        circle(80, 90)
        left(90)
    right(360/n)
hideturtle()
done()

 

 任务五

from turtle import *
setup(800, 600)
bgcolor('pink')
pencolor('yellow')
speed(0)
angle = 0
size = 2
n = 10
for i in range(n):
    for j in range(4):
        fd(size)
        angle += 72
        seth(angle)
        size += 2
hideturtle()
done()

 

 任务六

from random import random
from turtle import *
setup(800, 600)
speed(0)
penup()
goto(-80,0)
pendown()
right(180)
for i in range(20):
    color(tuple(random() for i in range(3)))
    begin_fill()
    for n in range(2):
        fd(8)
        right(90)
        fd(24)
        right(90)
    end_fill()
    penup()
    goto(-80+8*i+8, 0)
    pendown()
hideturtle()
done()
