[Python知识库]python turtle 绘制七段数码管以及14段数码管显示字母和时间

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

这里就直接修改了书上的代码,复制过去就可以用了.
小白一个,望大佬们多多指教
