Python directory file

Write a little every day, one day I can become more salty salted

Python in the operation of the file and directory is basically dependent on the Os,shutil module, which takes the main OS module, the most important examples of several methods are as follows:

1. Determine if the file/directory exists (os.path.exists (filename)), with the following example:

　　

Returns true if the file exists, false if not present

2. Get the current file path (OS.GETCWD ()) with the following example:

3. Delete the file (Os.remove ()) with the following example:

Delete a file to ensure that the file does exist

4. Modify the File/directory name (Os.rename ()) with the following example:

Modify file name needs to determine the existence of files

5. Traverse all the files in the directory (Os.walk), as shown in the following example:

1 #!/usr/bin/env python2 #-*-coding:utf-8-*-3 ImportOS4 5 6  forDirs,paths,namesinchOs.walk (OS.GETCWD ()):7      forPathinchpaths:8         PrintPath9 Ten      forNameinchnames: One         PrintOs.path.join (Dirs,path,name)

The output is as follows:

1 . idea2 D:\test_his\.idea\a.txt3 D:\test_his\.idea\b.txt4 D:\test_his\.idea\main.py5 D:\test_his\.idea\scrpy.py6 D:\test_his\.idea\test.py7 D:\test_his\.idea\test1.py8 Inspectionprofiles9 D:\test_his\.idea\inspectionProfiles\encodings.xmlTen D:\test_his\.idea\inspectionProfiles\misc.xml One D:\test_his\.idea\inspectionProfiles\modules.xml A D:\TEST_HIS\.IDEA\INSPECTIONPROFILES\TEST_HIS.IML - D:\test_his\.idea\inspectionProfiles\workspace.xml -D:\test_his\.idea\inspectionProfiles\inspectionProfiles\profiles_settings.xml

The rest of the methods and functions are described below:
