import turtle
turtle.shape(‘turtle‘)
turtle.speed(5)
turtle.color(‘green‘)
var=1
while var == 1:
      for i in range(5):
          turtle.forward(200)
          turtle.right(144)
   

無限循環的五角星

from turtle import*

for i in range(5）：
     up()
     goto(0,-20*i)
     down()
     circle(20*i)

　用循環畫同心圓

import turtle
turtle.shape(‘turtle‘)
turtle.speed(5)
turtle.color(‘yellow‘)
turtle.bgcolor(‘red‘)
turtle.fillcolor(‘yellow‘)

def my_goto(x,y):
    turtle.up()
    turtle.goto(x,y)
    turtle.down()

def my_star5(r):
    turtle.begin_fill()
    for i in range(5):
        turtle.forward(r)
        turtle.right(144)
        turtle.end_fill()

my_goto(-250,100)
my_star5(100)

my_goto(-150,75)
my_star5(50)

my_goto(-100,50)
my_star5(50)

my_goto(-50,25)
my_star5(50)

my_goto(-0,0)
my_star5(50)

用函數畫了五個五角星

import turtle

def draw_diamond(brad):
    brad.forward(100)
    brad.right(45)
    brad.forward(100)
    brad.right(135)

def draw_art():
    window=turtle.Screen()
    window.bgcolor("pink")

    brad=turtle.Turtle()
    brad.shape(‘turtle‘)
    brad.color(‘yellow‘)
    brad.speed(100)

    for i in range(1,37):
        draw_diamond(brad)
        draw_diamond(brad)
        brad.left(10)

draw_art()

畫一朵花

r = input("請輸入學號：")
print("學年:",r[:4])
print(r[4:6],":代表網絡工程")
print("學號:",r[10:12])

輸入學號識別年級專業序號

r = input("請輸入數字:")
print(‘星期‘,r)

　星期幾
