How can I rename a file in Python

Question

I am unable to rename my file using "refractor" option. Can it be done by writing a script or is there any other method to rename a file?

Answer 1

yes, you can use "os.rename" for that. Refer the below code:

import os

os.rename("a.py","test.py")

Here, a.py file has been renamed to "test.py" file.

1. import os
2.  
3. path = input("Enter the directory path where you need to rename: ")
4. for filename in os.listdir(path):
5. filename_without_ext = os.path.splitext(filename)[0]
6. extension = os.path.splitext(filename)[1]
7. new_file_name = filename_without_ext+"_n"
8. new_file_name_with_ext = new_file_name+extension
9. print(new_file_name_with_ext)
10. os.rename(os.path.join(path,filename),os.path.join(path,new_file_name_with_ext))

It worked for me.Test run the script to see if it works for you also. You can get back to me if any step is incorrect.

Here's a script based on your newest comment.

#!/usr/bin/env python
from os import rename, listdir

badprefix = "cheese_"
fnames = listdir('.')

for fname in fnames:
    if fname.startswith(badprefix*2):
        rename(fname, fname.replace(badprefix, '', 1))

Answer 5

Assuming you are already in the directory, and that the "first 8 characters" from your comment hold true always. (Although "CHEESE_" is 7 characters... ? If so, change the 8 below to 7)

from glob import glob
from os import rename
for fname in glob('*.prj'):
    rename(fname, fname[8:])

Answer 6

I have the same issue, where I want to replace the white space  in any pdf file to a dash -. But the files were in multiple sub-directories. So, I had to use os.walk(). In your case for multiple sub-directories, it could be something like this:

import os
for dpath, dnames, fnames in os.walk('/path/to/directory'):
    for f in fnames:
        os.chdir(dpath)
        if f.startswith('cheese_'):
            os.rename(f, f.replace('cheese_', ''))

Answer 7

You can use the os module and rename the file.
Import os
os.rename("old file","new file")
