How to resize multiple images from a folder, convert them into grayscale and save them into another folder?

I have written some code in Python for resizing and converting images to grayscale from a folder and want to save them in another folder. When I compile the code, it shows no output and gives no error. I am sharing the whole code that I have written so far so I can find my error. This is my first question here.

from PIL import Image               # to load images
from IPython.display import display # to display images
import cv2
import os
import glob
import numpy as np
img_path = r"C:\Users\usama\Documents\FYP-Data\FYP Project Data\hamza\h1.png"
im= Image.open(img_path)
print('{}'.format(im.format)) 
print('Size: {}'.format(im.size))
print('image mode:{}'.format(im.mode))
im.show()

img_list = []
resized_list = []
for filename in glob.glob(r'C:\Users\usama\Documents\FYP-Data\FYP Project Data\hamza\*.png'):
    print(filename)
    img=Image.open(filename)
    img_list.append(img)
    img_list=img_list[:2000]

for image in resized_list:
    if image not in resized_list:
        resized_list.append(img)
        resized_list=(resized_list[:2000])
        img=image.resize((500,500))
        rl=cv2.imread('resized_list') 
        gray_image = cv2.cvtColor(rl, cv2.COLOR_BGR2GRAY)
        cv2.imwrite('resized images *.png', gray_image)

Try the following:

import cv2
import glob

for filename in glob.glob(r'your\path\*.png'):
    print(filename)
    img=cv2.imread(filename) 
    rl=cv2.resize(img, (500,500))
    gray_image = cv2.cvtColor(rl, cv2.COLOR_BGR2GRAY)
    cv2.imwrite(f'{filename}.resized.png', gray_image)
