Python 最佳实践-观看目录的最佳方式是什么

试试看!从他们的例子来看:
import time
from watchdog.observers import Observer
from watchdog.events import LoggingEventHandler
event_handler = LoggingEventHandler()
observer = Observer()
observer.schedule(event_handler, path='/dir_name', recursive=True)
observer.start()
try:
while True:
time.sleep(1)
except KeyboardInterrupt:
observer.stop()
observer.join()
我成功地使用了PyPi中的
watcher
,它是APIReadDirectoryChangesW
的包装器。下面是一个示例(Py3,但它在Py2上运行):
可能重复的
from watcher import *
import time
def callback(*stuff):
if stuff[0] == FILE_ACTION_REMOVED:
print(stuff[1],"deleted")
else:
print(stuff)
w = Watcher('C:\\' , callback)
w.flags = FILE_NOTIFY_CHANGE_FILE_NAME
w.start()
while True:
time.sleep(100)
