篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了python turtle 绘制七段数码管以及14段数码管显示字母和时间相关的知识，希望对你有一定的参考价值。
书上的7段数码管,显示时间
书上的7断数码管显示应功都看过了,这里顺便提供一下`
import turtle, datetime
def drawGap(): #绘制数码管间隔
turtle.penup()
turtle.fd(5)
def drawLine(draw): #绘制单段数码管
drawGap()
turtle.pendown() if draw else turtle.penup()
turtle.fd(40)
drawGap()
turtle.right(90)
def drawDigit(d): #根据数字绘制七段数码管
drawLine(True) if d in [2,3,4,5,6,8,9] else drawLine(False)
drawLine(True) if d in [0,1,3,4,5,6,7,8,9] else drawLine(False)
drawLine(True) if d in [0,2,3,5,6,8,9] else drawLine(False)
drawLine(True) if d in [0,2,6,8] else drawLine(False)
turtle.left(90)
drawLine(True) if d in [0,4,5,6,8,9] else drawLine(False)
drawLine(True) if d in [0,2,3,5,6,7,8,9] else drawLine(False)
drawLine(True) if d in [0,1,2,3,4,7,8,9] else drawLine(False)
turtle.left(180)
turtle.penup()
turtle.fd(20)
def drawDate(date):
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))
def main():
turtle.setup(800, 350, 200, 200)
turtle.penup()
turtle.fd(-350)
turtle.pensize(5)
drawDate(datetime.datetime.now().strftime('%Y-%m=%d+'))
turtle.hideturtle()
main()
看看显示原理
我们把这里所有的False全部改为True,就可以明白7段是怎么绘制的了.
改完运行下,就知道了.
14段模型
参考下网上的14段图片
通过小学知识可以知道,这里我们得写14笔,完成一个14位数字管的.
画了一个顺序草图
大概就这样把,然后上代码就完事了.
14位数码管,画英文,和数字

运行就是这样啦,这里画了字母和数字
想画自己名字字母的,在name 里面添加名字字母的字符就行
下面又搞了个字体会变颜色的，还有背景闪烁的，嘿嘿
