用while循環畫太陽花

>>> from
 
 turtle import*
>>> color(‘red‘,‘blue‘)
>>> begin_fill()
>>> while True:
    forward(200)

用函數定義畫五個五角星

>>>import turtle
>>>turtle.setup(600,400)

>>>turtle.color("
 
yellow")
>>>turtle.bgcolor("red")
>>>turtle.fillcolor("yellow")
>>>turtle.speed(10)

>>>def turtle_goto(x,y):
  turtle.up()
  turtle.goto(x,y)
  turtle.down()
  
>>>def darw_star(d):
  turtle.begin_fill()
  for i in range(5):
      turtle.forward(d)
      turtle.right(
 
144)
      turtle.end_fill() 

>>>turtle_goto(-260,120)
>>>darw_star(120)

>>>turtle_goto(-110,160)
>>>turtle.left(40)
>>>darw_star(40)

>>>turtle_goto(-65,125)
>>>turtle.right(10)
>>>darw_star(40)

用函數定義畫鉆石花瓣的太陽花

>>>import turtle
>>>turtle.speed(30)
>>>turtle.color("green")

>>>def draw_rhombus(size):
    for i in range(2):
        turtle.fd(size)
        turtle.left(20)
        turtle.fd(size)
        turtle.left(160)

>>>turtle.right(90)

>>>turtle.begin_fill()
>>>for i in range(36):
    draw_rhombus(100)
    turtle.left(10)
>>>turtle.end_fill()
>>>turtle.fd(400)

輸入學號，識別年級、專業、序號

>>>name = input("請輸入名字：")
>>>num = input("請輸入學號：")

print("{}同學您好。".format(name))
print("您的年級為：{}級".format(num[0:4]))
>>>if(int(num[8:10])==43):
    print("您的班級為：網絡工程1班")
>>>elif(int(num[8:10])==44):
    print("您的班級為：網絡工程2班")
>>>elif(int(num[8:10])==41):
    print("您的班級為：軟件工程1班")
>>>elif(int(num[8:10])==42):
    print("您的班級為：軟件工程2班")
>>>print("您的序號為：{}".format(num[-2:]))

輸入1-7的數字，輸出對應的“星期幾”

>>>s="星期一星期二星期三星期四星期五星期六星期天"
>>>a=int(input("請輸入(1-7)："))
>>>if(0<a<8):
    print(s[-3+3*a:0+3*a])
>>>else:
    print("輸入有誤。")

識別身份證號中的省市區、年齡、性別

>>>ID=input(‘請輸入您的身份證號碼：‘)

>>>P=[‘廣東省‘,‘四川省‘]
>>>C=[‘廣州市‘,‘深圳市‘,‘成都市‘]
>>>R=[‘越秀區‘,‘白雲區‘,‘天河區‘,‘福田區‘,‘南山區‘,‘羅湖區‘]

>>>p=int(ID[0:2])
>>>c=int(ID[2:4])
>>>r=int(ID[4:6])
>>>sex=int(ID[16])
>>>age=int(ID[6:10])

>>>if p==44:
    print("您所屬的省：",P[0])
>>>elif p==51:
    print("您所屬的省：",P[1])
>>>else:
    print(‘查無數據。‘)

>>>if p==44:
    if c==1:
        print(C[0])   
>>>if r==4:
            print(D[0])
>>>elif r==11:
            print(D[1])
>>>elif  r==6:
            print(D[2])
>>>else:
             print(‘無數據。‘)
>>>elif c==3:
>>>if r==4:
            print(D[3])
