System cannot find the file specified when renaming image files

I have more than 1000 JPG images in a folder having different name. I want to rename images as 0.JPG, 1.jpg, 2.jpg...

I tried different code but having below error:

The system cannot find the file specified: 'IMG_0102.JPG' -> '1.JPG'

The below code is one the codes found in this link: Rename files sequentially in python

import os
_src = "C:\\Users\\sazid\\Desktop\\snake"
_ext = ".JPG"
for i,filename in enumerate(os.listdir(_src)):
    if filename.endswith(_ext):
        os.rename(filename, str(i)+_ext)

How to solve this error. Any better code to rename image files in sequential order?

Solution

  • just use glob and save yourself the headache

    with glob your code turns into this:

    import os
from glob import glob

target_dir = './some/dir/with/data'

for i, p in enumerate(glob(f'{target_dir}/*.jpg')):
    os.rename(p, f'{target_dir}/{i}.jpg')

    in this code glob() gives you a list of found file paths for files that have the .jpg extension, hence the *.jpg pattern for glob, here is more on glob
