Python's Directory file operation

[1.os]

1. Renaming: Os.rename (old, new)

2. Delete: Os.remove (file)

3. List the directories underFile: Os.listdir (PATH)

4. Get current working directory: OS.GETCWD ()

5. Change of working directory: Os.chdir (newdir)

6. Create a multilevel directory: Os.makedirs (r "c:/Python/test ")

7. Create a single directory: Os.mkdir ("Test")

8. Delete Multiple directories: Os.removedirs (r "C:/python") #删除所给路径最后一个目录下所有空目录.

9. Delete a single directory: Os.rmdir ("Test")

10. Get File attributes: Os.stat (file)

11. Modify file permissions and timestamps: Os.chmod (file)

12. Perform the actionSystem command: Os.system ("dir")

13. Start a new process: Os.exec (), OS.EXECVP ()

14. Executing the program in the background: OSSPAWNV ()

15. Terminate the current process: Os.exit (), Os._exit ()

16. Detach file Name: Os.path.split (r "c:/python/hello.py")--("C://python", "hello.py")

17. Detach Extension: Os.path.splitext (r "c:/python/hello.py")--("C://python//hello", ". Py")

18. Get path name: Os.path.dirname (r "c:/python/hello.py")--"C://python"

19. Get File Name: Os.path.basename (r "r:/python/hello.py")--"hello.py"

20. Determine if the file exists: os.path.exists (r "c:/python/hello.py")---True

21. Determine if absolute path: Os.path.isabs (r "./python/")---False

22. Determine if it is a directory: Os.path.isdir (r "C:/python")--True

23. Determine if it is a file: Os.path.isfile (r "c:/python/hello.py")---True

24. Determine if it is a linked file: Os.path.islink (r "c:/python/hello.py")---False

25. Get File Size: os.path.getsize (filename)

26.*******:os.ismount ("c://")--True

27. Search all files in directory: Os.path.walk ()

[2.shutil]

1. Copying individual files: shultil.copy (Oldfile, Newfle)

2. Copy Entire directory tree: Shultil.copytree (r "./setup", R "./backup")

3. Delete entire directory tree: Shultil.rmtree (r "./backup")

[3.tempfile]

1. Create a unique temporary file: tempfile.mktemp ()---filename

2. Open temporary file: tempfile. Temporaryfile ()

[4.StringIO] #cStringIO是StringIO模块的快速实现模块

1. Creatememory file and write initial data: F = Stringio.stringio ("Hello world!")

2. Read in memory file data: Print F.read () #或print f.getvalue ()--Hello world!

3. Want the memory file to write data: F.write ("Good day!")

4. Close the memory file: F.close ()
