Help with program for renaming files

Python Help
1

hello i’m new here .recently i was trying to improve my work life since it is really tiring to getting those bunch on files to be renamed . after 2 days working I realized there is a pattern for those file that rename before and after.

this the code I work with

import os

folder_path = r’D:\CSL excel\New folder’

intro_count = 1
full_count = 1
previous_file_renamed = None
last_renamed_ext = None

for dirpath, dirnames, filenames in os.walk(folder_path):
subfolder_name = os.path.basename(dirpath)
for filename in sorted(filenames):
file_path = os.path.join(dirpath, filename)
name, ext = os.path.splitext(filename)


    if ext == '.mp3':
        if last_renamed_ext == '.jpg' and 'FOTO_STNK' in name:
            new_name = f'{subfolder_name} STNK.mp3'
            previous_file_renamed = 'STNK'
        elif previous_file_renamed == None or previous_file_renamed.startswith('intro'):
            new_name = f'{subfolder_name} intro {intro_count}.mp3'
            intro_count += 1
            previous_file_renamed = 'intro'
        elif previous_file_renamed == 'misscall':
            new_name = f'{subfolder_name} STNK.mp3'
            previous_file_renamed = 'STNK'
        elif previous_file_renamed == 'STNK':
            new_name = f'{subfolder_name} Full {full_count}.mp3'
            full_count += 1
            previous_file_renamed = 'Full'
        else:
            new_name = f'{subfolder_name} Full {full_count}.mp3'
            full_count += 1
    elif ext == '.jpg':
        if 'FOTO_RESP' in name:
            new_name = f'{subfolder_name} misscall.jpg'
            previous_file_renamed = 'misscall'
        elif 'FOTO_STNK' in name:
            new_name = f'{subfolder_name} STNK.jpg'
            previous_file_renamed = 'STNK'
        elif 'GIFT_FOTO_GIFT' in name:
            new_name = f'{subfolder_name} gift.jpg'
            previous_file_renamed = 'gift'
    else:
        continue
    
    last_renamed_ext = ext
    new_path = os.path.join(dirpath, new_name)
    if not os.path.exists(new_path):
        os.rename(file_path, new_path)


    new_path = os.path.join(dirpath, new_name)
    if not os.path.exists(new_path):
        os.rename(file_path, new_path)

this is work but not as i intended.

Please wrap code in triple backticks to preserve the formatting:

```
if True:
    print(''Hello world!')
```

You can do that by selecting the code and then clicking the </> button.

It’s difficult to tell because of the messed-up formatting, but I think the problem is with this:

elif previous_file_renamed == None or previous_file_renamed.startswith('intro'):

You’re initialising previous_file_renamed = None before the first loop, so the condition is true for the first few of the files of the first folder.

However, after finishing that folder, it still has its last value, which is neither None nor 'intro'.

Therefore, for the second folder, the condition won’t be true for the first few files.

The fix is to reset previous_file_renamed back to None (if I understand the code correctly). Just move that line inside the outer loop.
