python实现截取屏幕保存文件,删除N天前截图的例子

 from PIL import ImageGrab import time import schedule import os import shutil import datetime days = -3 # 截屏 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-600') # 删除文件 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)
