Python mkdir一个有难度的问题

Question

在编辑器里我写了os.mkdir(XXXXX)这里是绝对路径
那么我接下来的代码里该如何获取到这个路径，现在假装我看不见XXXX是什么了（眼睛瞎了）
用Python不用其他。

貌似题主的意思是想监听文件的事件
Linux上监听文件事件使用inotify。对inotify的简单介绍，摘录自baidu：
http://baike.baidu.com/link?url=q_BEqnf6L7kdjx2-kdEOADCl3iEZbvhW_Gx_WDh3Z4xSfZZJ0MQPNn6H6IVOHoBQHjglPZfaU5R68IqM9L57-a

Inotify 是一个 Linux 内核特性，它监控文件系统，并且及时向专门的应用程序发出相关的事件警告，比如删除、读、写和卸载操作等。您还可以跟踪活动的源头和目标等细节。
使用 inotify 很简单：创建一个文件描述符，附加一个或多个监视器（一个监视器 是一个路径和一组事件），然后使用 read 方法从描述符获取事件。read 并不会用光整个周期，它在事件发生之前是被阻塞的。
更好的是，因为 inotify 通过传统的文件描述符工作，您可以利用传统的 select 系统调用来被动地监控监视器和许多其他输入源。两种方法 — 阻塞文件描述符和使用 select— 都避免了繁忙轮询。

python对应的监听文件事件的lib为pyinotify ，由于mac上安装不了inotify，所以直接在网上找的代码，供题主参考；原连接为：http://www.tuicool.com/articles/fQ7bUr；
思路：通过pyinotify监听文件事件，通过轮询文件事件，来做相应的处理；按照生产者消费者的模型处理，生产者轮询文件事件，放进共享队列；消费者轮询消费共享队列中的数据。

[root@centos6 monitor-folder]# python total-monitor.py
OPEN event: /tmp/.ICE-unix

OPEN event: /tmp
CLOSE_NOWRITE event: /tmp
OPEN event: /tmp

CLOSE_WRITE event: /tmp/bb

CLOSE_WRITE event: /tmp/cc

上面是打印出来的监控状态，下面是我的操作代码：

[root@centos6 tmp]# ls
aa            bash.bashrc             ipt.err    odbcinst.ini    wgetrc
adduser.conf  bindresvport.blacklist  ipt.out    timezone        xinetd.conf
adjtime       environment             krb5.conf  ucf.conf
aliases       fstab                   odbc.ini   warnquota.conf
[root@centos6 tmp]# rm -rf *
[root@centos6 tmp]# touch aa
[root@centos6 tmp]# touch bb
[root@centos6 tmp]# touch cc
[root@centos6 tmp]# 

    

Answer 2

用个变量不就完了？

path='/tmp/test'
os.mkdir(path)
print(path)

Answer 3

目测题主想表达运行程序的时候动态获取当前程序文件的绝对路径。

$ vim test.py

import os

current_path = os.path.abspath(os.path.curdir)
new_dir = 'XXX'
new_dir_path = os.path.join(current_path, new_dir)
os.mkdir(new_dir_path)

$ python test.py
