如何通过修改函数输出样例

import time
import turtle
def drawGap():
    turtle.penup()
    turtle.fd(5)
def drawLine(draw):
    drawGap()
    turtle.pendown() if draw else turtle.penup()
    turtle.fd(40)
    drawGap()
    turtle.right(90)
def drawDigit(dight):
    drawLine(True) if dight in [2,3,4,5,6,8,9]else drawLine(False)
    drawLine(True) if dight in [0,1,3,4,5,6,7,8,9] else drawLine(False)
    drawLine(True) if dight in [0,2,3,5,6,8,9] else drawLine(False)
    drawLine(True) if dight in [0,2,6,8] else drawLine(False)
    turtle.left(90)
    drawLine(True) if dight in [0,4,5,6,8,9] else drawLine(False)
    drawLine(True) if dight in [0,2,3,5,6,7,8,9] else drawLine(False)
    drawLine(True) if dight in [0,1,2,3,4,7,8,9] else drawLine(False)
    turtle.left(180)
    turtle.penup()
    turtle.fd(20)
def drawBefore():
    turtle.right(90)
    turtle.fd(60)
    turtle.left(90)
def drawAfter():
    turtle.left(90)
    turtle.fd(60)
    turtle.right(90)
def drawDate():#date为日期,格式为'%y-%m+%d='
    for i in date:
        if i == '-':
            #绘制年
            drawBefore()
            turtle.write('年',font=("Arial",18,"normal"))
            turtle.pencolor("green")
            turtle.fd(40)
            drawAfter()
        elif i =='+':
            #绘制月
            drawBefore()
            turtle.write('月', font=("Arial", 18, "normal"))
            turtle.pencolor("blue")
            turtle.fd(40)
            drawAfter()
        elif i == '=':
            #绘制日
            drawBefore()
            turtle.write('日', font=("Arial", 18, "normal"))
        else:
            drawDigit(eval(i))

def main():
    turtle.setup(1200,350,200,200)
    turtle.penup()
    turtle.fd(-300)
    turtle.pensize(5)
    turtle.pencolor("red")
    date=time.strftime('%Y-%m+%d=',time.gmtime(), 202113501019)
    drawDate(501019)
    turtle.hideturtle()
    turtle.done()
main()

在turtle画板中输出202113501019这串数字
怎样修改main函数和drawDate函数

这个代码只能输出年月日，代码如下，如有用请采纳

import time
import turtle
def drawGap():
    turtle.penup()
    turtle.fd(5)
def drawLine(draw):
    drawGap()
    turtle.pendown() if draw else turtle.penup()
    turtle.fd(40)
    drawGap()
    turtle.right(90)
def drawDigit(dight):
    drawLine(True) if dight in [2,3,4,5,6,8,9]else drawLine(False)
    drawLine(True) if dight in [0,1,3,4,5,6,7,8,9] else drawLine(False)
    drawLine(True) if dight in [0,2,3,5,6,8,9] else drawLine(False)
    drawLine(True) if dight in [0,2,6,8] else drawLine(False)
    turtle.left(90)
    drawLine(True) if dight in [0,4,5,6,8,9] else drawLine(False)
    drawLine(True) if dight in [0,2,3,5,6,7,8,9] else drawLine(False)
    drawLine(True) if dight in [0,1,2,3,4,7,8,9] else drawLine(False)
    turtle.left(180)
    turtle.penup()
    turtle.fd(20)
def drawBefore():
    turtle.right(90)
    turtle.fd(60)
    turtle.left(90)
def drawAfter():
    turtle.left(90)
    turtle.fd(60)
    turtle.right(90)
def drawDate(date):#date为日期,格式为'%y-%m+%d='
    for i in date:
        if i == '-':
            #绘制年
            drawBefore()
            turtle.write('年',font=("Arial",18,"normal"))
            turtle.pencolor("green")
            turtle.fd(40)
            drawAfter()
        elif i =='+':
            #绘制月
            drawBefore()
            turtle.write('月', font=("Arial", 18, "normal"))
            turtle.pencolor("blue")
            turtle.fd(40)
            drawAfter()
        elif i == '=':
            #绘制日
            drawBefore()
            turtle.write('日', font=("Arial", 18, "normal"))
        else:
            drawDigit(eval(i))
 
def main():
    turtle.setup(1200,350,200,200)
    turtle.penup()
    turtle.fd(-300)
    turtle.pensize(5)
    turtle.pencolor("red")
#     date=time.strftime('%Y-%m+%d=',time.gmtime())
    date = '2021-03+01='
    drawDate(date)
    turtle.hideturtle()
    turtle.done()
main()
