七段数码管绘制步骤

　　　　引入turtle库

　　　　-一个数字的绘制

　　　　-多个数字的绘制

　　　　-时间数码管的绘制

import time
import turtle


def drawGap():
    turtle.penup()
    turtle.fd(5)


def drawLine(draw):  # 定义一个函数，只要满足draw有值，就画线
    drawGap()
    turtle.pendown() if draw else turtle.penup()
    turtle.fd(40)
    drawGap()
    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):  # date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))


def main():
    turtle.setup(800, 350, 200, 200)  # 设定画布的大小，位置
    turtle.penup()
    turtle.fd(-300)
    turtle.pensize(5)
    drawDate(time.strftime("%Y-%m=%d+", time.gmtime()))
    turtle.hideturtle()
    turtle.done()


main()  # 调用主函数
