我就廢話不多說，直接上程式碼吧！

from PIL import ImageGrab
import time
import schedule
import os
import shutil
import datetime

days = -3
# 截圖
def savepic():
 im = ImageGrab.grab()
 now = time.strftime("%Y_%m_%d_%H_%M_%S",time.localtime())
 day = time.strftime("%Y%m%d",time.localtime())
 file_path_top = 'c:\\tmp\\'
 if not os.path.exists(file_path_top):
  os.mkdir(file_path_top)
 file_path = 'c:\\tmp\\'+day+'\\'
 if not os.path.exists(file_path):
  os.mkdir(file_path)
 im.save(file_path+now+'.jpg')

# 刪除檔案
def deletefile(): 
 today = datetime.datetime.now()
 offset = datetime.timedelta(days=days)
 re_date = today + offset
 file_dir = r'C:\tmp'
 for root,dirs,files in os.walk(file_dir):
  for i in dirs:
   if(i<=re_date.strftime('%Y%m%d')):
    path = 'C:\\tmp\\'+i
    if (os.path.exists(path)):
     shutil.rmtree(path)
         
schedule.every(60).seconds.do(savepic)
schedule.every().day.at("00:30").do(deletefile)
while True:
  schedule.run_pending()
  time.sleep(1)

以上這篇python實現擷取螢幕儲存檔案,刪除N天前截圖的例子就是小編分享給大家的全部內容了，希望能給大家一個參考，也希望大家多多支援我們。
