Python3 batch file rename operation example

rename () method syntax is as follows:

os.rename(old，new)

old is a need to modify the directory / file names, new directory is modified / file name, by this method we can easily complete the bulk of the increase in fixed prefix file / directory or batch delete the file / directory fixed prefix.

The following code under Windows and Linux can be used.

Examples are as follows:

Prefixed '[Linuxidc.]':

import os
path='/home/linuxidc/linuxidc.com'
old_dir=os.listdir(path) #获取/home/linuxidc/linuxidc.com目录下的所有文件目录
print("原始目录为 %s"%old_dir)
for i in old_dir:
    new_name='[Linuxidc.]'+i
    os.rename(i,new_name)
new_dir=os.listdir(path)
print("现在的目录为%s"%new_dir)

After running output:

Delete the prefix '[Linuxidc.]':

import os
path='/home/linuxidc/linuxidc.com'
old_dir=os.listdir(path)
print("原始目录为 %s"%old_dir)
for i in old_dir:
    shu=i.rfind(']') #获取到']'的位置
    new_name=i[shu+1:]
    os.rename(i,new_name)
new_dir=os.listdir(path)
print("现在的目录为%s"%new_dir)

After running output:

In Windows also need to look at the file path should use double slashes //, or an error, this error under Linux generally does not occur.
