rename or replace the files in a folder

Question

I have a folder contains images. each image named as

abc_001.jpg 
abc_002.jpg 

I need to rename the images by deleting the first text abc_ and start from the number

I did as

import os

path = '/Desktop/my_folder'

folder = os.fsencode(path)

filenames = []

for file in os.listdir(folder):
    filename = os.fsdecode(file)
    if filename.endswith ('.jpg'):
          filenames=filename.replace('abc_','')

but it doesn't work . how can I replace the first text or deleting them?

i tried

for file in os.listdir(folder):
    filename = os.fsdecode(file)
    if filename.endswith ('.jpg'):
        filenames = filename.replace('abc_', '')
        os.rename(filename, filenames)

but got

 os.rename(filename, filenames)
FileNotFoundError: [Errno 2] No such file or directory: 'abc_000000000009.jpg' -> '000000000009.jpg'

Answer 1

I solved the problem so anyone who faces the same problem can try it

for file in os.listdir(folder):
    filename = os.fsdecode(file)
    if filename.endswith ('.jpg'): 
        filenames = filename.replace('abc_', '')
        os.rename(os.path.join(path,filename), os.path.join(path,filenames))
