Python初学者日志 7段数码管绘制Demo

import turtle
#绘制单个线条
def drawLine(draw):
    turtle.pendown() if draw else turtle.penup()
    turtle.fd(40)
    turtle.right(90)
#绘制整个数字及整个时间数字段
def drawDigit(digit):
    drawLine(True) if digit in [2, 3, 4, 5, 6, 8, 9] else drawLine(False)
    drawLine(True) if digit in [0, 1, 3, 4, 5, 6, 7, 8, 9] else drawLine(False)
    drawLine(True) if digit in [0, 2, 3, 5, 6, 8, 9] else drawLine(False)
    drawLine(True) if digit in [0, 2, 6, 8] else drawLine(False)
    turtle.left(90)
    drawLine(True) if digit in [0, 4, 5, 6, 8, 9] else drawLine(False)
    drawLine(True) if digit in [0, 2, 3, 5, 6, 7, 8, 9] else drawLine(False)
    drawLine(True) if digit in [0, 1, 2, 3, 4, 7, 8, 9] else drawLine(False)
    turtle.right(180)
    turtle.penup()
    turtle.fd(20)
    turtle.pendown()
#对时间数字段中单个的数字进行处理
def drawData(data):
    for i in data:
        drawDigit(eval(i))
#设置基本绘制环境
def main():
    turtle.setup(800, 350, 200, 200)
    turtle.penup()
    turtle.fd(-300)
    turtle.pensize(5)
    drawData('20180730')
    turtle.hideturtle()
    turtle.done()

main()

下面为更好绘制效果的实现：

1、增加绘制的数码效果，也就是线段间隔效果

#间隔设置
def drawGap():
    turtle.penup()
    turtle.fd(5)

def drawLine(draw):
#在绘制线段之前和之后都填上一段间隔
    drawGap()
    turtle.pendown() if draw else turtle.penup()
    turtle.fd(40)
    drawGap()
    turtle.right(90)

2、获取系统时间

（main函数中）

drawData(time.strftime('%Y-%m=%d+', time.gmtime()))

3、年月日的表示、颜色统一

def drawData(data):
#年的颜色为tomato
    turtle.pencolor("tomato")
    for i in data:
#四组判断
        if i == '-':
            turtle.write('年', font = ("Arial", 25, "normal"))
#月的颜色为黄色
            turtle.pencolor("yellow")
            turtle.fd(90)
        elif i =='=':
            turtle.write('月', font = ("Arial", 25, "normal"))
#日的颜色为蓝色
            turtle.pencolor("blue")
            turtle.fd(90)
        elif i =='+':
            turtle.write('日', font = ("Arial", 25, "normal"))
        else:
            drawDigit(eval(i))
