我用pyinotify监控一个目录，当我用cp拷贝一个文件夹(内含多级子目录)到监控目录时，仅仅监控到create事件，我需要的IN_CLOSE_WRITE事件没有监控到，
但是如果我cp的目录没有子目录，其下仅有文件时又能获取IN_CLOSE_WRITE事件。。
我这里是在事件里面加了些过滤以及判断，如果去掉这些过滤和判断，单独针对某一个事件设定执行动作就木有问题。
请问有什么合适的方式实现过滤掉某些文件？
监控的事件样例输出如下：

IN_CLOSE_WRITE : a writable file was closed
只有fileclosed的时候会触发IN_CLOSE_WRITE, directory不会触发此事件.
