基本思路:
1.绘制单个数字对应的数码管
2.获得一串数字,绘制对应的数码管
3.获得当前系统时间,绘制对应的数码管
七段数码管对应线条:
首先,绘制单个数字对应的数码管函数:
def drawGap():#绘制数码管间隔
turtle.penup()
turtle.fd(5)
def drawLine(draw):
drawGap()
if (draw):
turtle.pendown()
else:
turtle.penup()
turtle.fd(40)
turtle.right(90)
之后,根据数字绘制七段数码管:
def drawDigit(digit):#根据数字绘制七段数码管
if digit in [2,3,4,5,6,8,9]:#1
drawLine(True)
else:
drawLine(False)
if digit in [0,1,3,4,5,6,7,8,9]:#2
drawLine(True)
else:
drawLine(False)
if digit in [0,2,3,5,6,8,9]:#3
drawLine(True)
else:
drawLine(False)
if digit in [0,2,6,8]:#4
drawLine(True)
else:
drawLine(False)
turtle.left(90)#左转90度
if digit in [0,4,5,6,8,9]:#5
drawLine(True)
else:
drawLine(False)
if digit in [0,2,3,5,6,7,8,9]:#6
drawLine(True)
else:
drawLine(False)
if digit in [0,1,2,3,4,7,8,9]:#7
drawLine(True)
else:
drawLine(False)
turtle.left(180)
turtle.penup()#为绘制后续数字确定位置
turtle.fd(20)#为绘制后续数字确定位置
将数字串转换成单个数字:
def drawDate(date):
for i in date:
drawDigit(eval(i))
定义主函数:
def main():
turtle.setup(800,350,200,200)
turtle.penup()
turtle.fd(-300)
turtle.pensize(10)
drawDate('20200630')
turtle.hideturtle()
turtle.done()
程序运行结果如下:
接下来,获得当前系统时间,用于绘制对应的数码管。
修改drawDate函数:
def drawDate(date):#data为日期,格式为‘%Y-%m=%d+’
turtle.pencolor("red")
for i in date:
if i=='-':
turtle.write('年',font=('Arial',18,"normal"))
turtle.pencolor("green")
turtle.fd(40)
elif i=='=':
turtle.write('月',font=('Arial',18,"normal"))
turtle.pencolor("blue")
turtle.fd(40)
elif i=='+':
turtle.write('日',font=('Arial',18,"normal"))
else:
drawDigit(eval(i))
主函数:
def main():
turtle.setup(800,350,200,200)
turtle.penup()
turtle.fd(-300)
turtle.pensize(10)
drawDate(time.strftime('%Y-%m=%d+',time.gmtime()))
turtle.hideturtle()
turtle.done()
修改后的程序结果如图:
