Python程序设计学习笔记-中国大学MOC-举一反三-七段数码管绘制-带小数点 #中国大学MOOC# #Python语言程序设计# #北京理工大学# #嵩天##七段数码管绘制##带小数点# 才学习完MOC网嵩天老师的python第五周的课，课堂上老师是用turtle库和time库，获取系统时间，绘制七段数码管来表达年月日的。举一反三思考如何实现带小数点的七段数码管的绘制？之前也只学习了用turtle库绘制图形，想到了直接利用画圆点的方法来实现，感觉还是挺笨的[捂脸] 1.首... 阅读详情

# SevenDigitsDrawV1.py
import turtle
def drawLine(draw):  # 绘制单段数码管
    turtle.pendown() if draw else turtle.penup()
    turtle.fd(40)
    turtle.right(90)
def drawDigit(digit):  # 根据数字绘制七段数码管
    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.left(180)
    turtle.penup()
    turtle.fd(20)
def drawDate(date):  # 获得要输出的数字
    for i in date:
        drawDigit(eval(i))  # 通过eval()函数将数字变为整数
def main():
    turtle.setup(800, 350, 200, 200)
    turtle.penup()
    turtle.fd(-300)
    turtle.pensize(5)
    drawDate('20181010')
    turtle.hideturtle()
    turtle.done()
main()

在这里插入图片描述

    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)

    drawLine(True) if d in [2, 3, 4, 5, 6, 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.penup()
    turtle.fd(20)

    turtle.pencolor("red")

            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))

    #    drawDate('2018-10=10+')
    drawDate(time.strftime('%Y-%m=%d+', time.gmtime()))
