python获取文件的创建时间

Linux下使用st_ctime近似获取文件的创建时间，适用于文件创建后不发生任何变化的情况

filectime = os.stat(strUrl+filename).st_ctimedatetime.datetime.fromtimestamp(filectime).strftime('%Y-%m-%d-%H-%M-%S-%f')

The field st_ctime is changed by writing or by setting inode information (i.e., owner, group, link count, mode, etc.).
