Detailed explanation of the renames method of the os module
This article mainly introduces the relevant information about the powerful renaming method renames of the os module under python. Friends who need it can refer to
The powerful renaming method renames of the os module under python is explained in detail.
There are many powerful modules in python, among which we often use the OS module. The OS module provides more than 200 methods for us to use, and these methods are all related to data processing. Yes, here is the renaming method.
The renaming method of OS is os.rename. I use ipython. This thing is very powerful. As long as the TAB key is pressed, it can help us automatically align and list the methods that can be used. I found There are 2 methods, namely rename and renames, 2 methods. The former rename has been used countless times, but the latter renames has not been used yet. I have free time today and want to see how useful it is---As the name suggests, I think Maybe it’s batch modification, haha, let’s take a look at the demonstration effect:
[root@localhost ~]# ipython 进入ipython工具

In [1]: import os 导入OS模块
In [2]: os.mkdir("/tmp/test") 新建目录
In [3]: os.listdir("/tmp/test")
Out[3]: []
In [4]: os.mkdir("/tmp/test/test1") 新建目录
In [5]: os.listdir("/tmp/test/")
Out[5]: ['test1']
In [6]: os.listdir("/tmp/test/test1")
Out[6]: []
In [7]: os.ren 按Tab键自动对齐的效果
os.rename os.renames
In [7]: os.rename("/tmp/test/test1","/tmp/test/test2")
重命名目录名
In [8]: os.listdir("/tmp/test/") 修改成功
Out[8]: ['test2']
In [9]: os.rename 按Tab键自动对齐的效果
os.rename os.renames
In [9]: os.rename("/tmp/test/test2","/tmp/test1/test3")
大家注意看下这个命令和上面的命令的区别，我不仅仅是要重命名最后的目录名，连前面的目录也要重命名
---------------------------------------------------------------------------
OSError Traceback (most recent call last)
/root/<ipython console> in <module>()
OSError: [Errno 2] No such file or directory
嘿嘿，报错了，说没有这个目录，
下面在看下下面这个强大的方法吧，哈哈
In [10]: os.renames("/tmp/test/test2","/tmp/test1/test3")
In [11]: os.listdir("/tmp/test1/test3")
Out[11]: []
嘿嘿，居然成功了，真是强大啊，子目录能改，上级目录也能改，这个法子也许对我们工作会有帮助吧。
In [12]: os.listdir("/tmp/test1")
Out[12]: ['test3']Similarly, he can modify the directory name, but I don’t know if it can modify the file name and directory name at the same time. Let’s take a look below. The following effect:
In [22]: os.listdir("/tmp/test1/test3/")
Out[22]: ['test'] 新建一个空文件
In [23]: cat /tmp/test1/test3/test
In [24]: os.renam
os.rename os.renames
In [24]:
os.renames("/tmp/test1/test3/test","/tmp/test/test2/test3")
批量修改文件名和目录名，嘿嘿，果然也成功了。
In [25]: os.listdir("/tmp/test/test2/test3")
---------------------------------------------------------------------------
OSError Traceback (most recent call last)
/root/<ipython console> in <module>()
OSError: [Errno 20] Not a directory: '/tmp/test/test2/test3'
In [26]: os.listdir("/tmp/test/test2/") 浏览效果
Out[26]: ['test3']
