Py file operations

1. OS]

1. Rename: OS. Rename (old, new)

2. Delete: OS. Remove (file)

3. List the files in the directory: OS. listdir (PATH)

4. Get the current working directory: OS. getcwd ()

5. Change the 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") # delete all empty directories in the last directory of the given path.

9. delete a single directory: OS. rmdir ("test ")

10. Get file attributes: OS. Stat (file)

11. Modify the File Permission and timestamp: OS. chmod (file)

12. Execute the operating system command: OS. System ("dir ")

13. Start a new process: OS .exe C (), OS .exe CVP ()

14. Execute the program in the background: osspawnv ()

15. Terminate the current process: OS. Exit (), OS. _ exit ()

16. Separated file name: OS. Path. Split (R "C:/Python/Hello. py") --> ("C: // Python", "Hello. py ")

17. separation Extension: OS. path. splitext (R "C:/Python/hello. PY ") --> (" C: // Python // hello ",". PY ")

18. Obtain the path name: OS. Path. dirname (R "C:/Python/Hello. py") --> "C: // Python"

19. Get the file name: OS. Path. basename (R "R:/Python/Hello. py") --> "Hello. py"

20. Determine whether the file exists: OS. Path. exists (R "C:/Python/Hello. py") --> true

21. Determine whether the path is absolute: OS. Path. isabs (R "./Python/") --> false

22. Check whether the directory is OS. Path. isdir (R "C:/Python") --> true

23. Determine whether the file is: OS. Path. isfile (R "C:/Python/Hello. py") --> true

24. Determine whether the file 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 the directory: OS. Path. Walk ()

[2. shutil]

1. Copy a single file: shultil. Copy (oldfile, newfle)

2. Copy the entire directory tree: shultil. copytree (R "./setup", R "./backup ")

3. Delete the entire directory tree: shultil. rmtree (R "./backup ")

[3. tempfile]

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

2. Open the temporary file: tempfile. temporaryfile ()

[4. stringio] # cstringio is a fast implementation module of the stringio module.

1. Create a memory file and write the initial data: F = stringio. stringio ("Hello world! ")

2. Read Memory file data: Print F. Read () # or print F. getvalue () --> Hello world!

3. Write Data to memory files: f. Write ("good day! ")

4. Close the memory file: f. Close ()

[5. glob]

1. Matching file: Glob. glob (R "C:/Python/*. py ")
