【问题描述】：

我正在从事一个项目，我想创建一个将在电子纸显示器上显示的日历。我设法制作了网格，但不知道如何用日历日期填充网格。网格位于显示屏的下半部分，因为我使用上半部分显示天气信息。

此代码用于创建稍后将传输到显示器的图像。

如果可能的话，我想在左侧从星期日开始的网格中显示当前月份的日期。

请指教

这是我的代码：

from PIL import Image, ImageDraw, ImageFont
import datetime
from datetime import date
from calendar import monthrange 

import calendar



w, h = 480, 800

img = Image.new("RGB",(w,h), (255,255,255))
draw = ImageDraw.Draw(img)

boarder = 9
h_start= int(h/2)
h_end = int(h-boarder)
w_start = boarder
w_end = w-boarder
stepsizeV = int((w-2*boarder)/7)
stepsizeH = int((h_start-boarder)/5)

#draw.rectangle((10,h_start,w-10,h_end),outline=1,width=5,)
for x in range (boarder,w,stepsizeV):
    line = ((x,h_start),(x,h_end))
    draw.line(line,fill=1,width=3)
for x in range (h_start,h,stepsizeH):
    line = ((w_start,x),(w_end,x))
    draw.line(line,fill=50, width=3)

Curdate = date.today() 
date =int(Curdate.strftime('%d'))
month = int(Curdate.strftime('%m'))
year = int(Curdate.strftime('%y'))

monthlen = calendar.monthrange(year,month)

for i in range (monthlen):
    for j in range(7):
    

【参考方案1】：

from PIL import Image, ImageDraw, ImageFont

from datetime import date
from calendar import monthrange 

import calendar

w, h = 480, 800

img = Image.new("RGB",(w,h), (255,255,255))
draw = ImageDraw.Draw(img)

boarder = 9
h_start= int(h/2)
h_end = int(h-boarder)
w_start = boarder
w_end = w-boarder
stepsizeV = int((w-2*boarder)/7)
stepsizeH = int((h_start-boarder)/5)

#draw.rectangle((10,h_start,w-10,h_end),outline=1,width=5,)
cols=[]
rows=[]
days =  0:'Sun', 1:'Mon', 2:'Tue', 3:'Wed', 4:'Thu', 5:'Fri', 6:'Sat'
i=0
for x in range (boarder,w,stepsizeV):
    line = ((x,h_start),(x,h_end))
    draw.line(line,fill=1,width=3)
    cols.append(x+stepsizeV/2)
    if i<7:
        draw.text((x+stepsizeV/2 -10, h_start-stepsizeV/2), days[i], fill=(0,0,0))
        i+=1

for x in range (h_start,h,stepsizeH):
    line = ((w_start,x),(w_end,x))
    draw.line(line,fill=50, width=3)
    rows.append(x+stepsizeH/2)

Curdate = date.today() 
date =int(Curdate.strftime('%d'))
month = int(Curdate.strftime('%m'))
year = int(Curdate.strftime('%y'))

monthlen = calendar.monthrange(year,month)

k = monthlen[0] + 1
i=1
j=0
r = rows[j]
while i<= monthlen[1]:
    c = cols[k]
    draw.text((c,r), str(i), fill=(0,0,0))
    i+=1
    k = (k+1)%7
    if not k:
        j+=1
        r = rows[j]
img.show()
