Posted 2023-05-13

参考技术A import os, time
path_to_watch = "."before = dict ([(f, None) for f in os.listdir (path_to_watch)])while 1:
time.sleep (10)
after = dict ([(f, None) for f in os.listdir (path_to_watch)])
added = [f for f in after if not f in before]
removed = [f for f in before if not f in after] if added: print "Added: ", ", ".join (added) if removed: print "Removed: ", ", ".join (removed)
before = after 参考技术B 通过写代码

如何用Lua.EXE调用Lua文件啊？

参考技术A prompt>是命令行提示符，跟它操作系统用的控制台有点关系，一般代表目录名或帐号名一类的东西。
