转换图像时出现错误权限 13

Question

I try to convert all images from my directory in webp using a python script but when I try to use function I get this error: Permission error 13

from PIL import Image
import PIL
import os
import glob

files = os.listdir()

images = [file for file in files if file.endswith(('jpg', 'png', 'jfif', 'jpeg'))]

print(f"Images {images}")

images = [file for file in files if file.endswith(('jpg', 'png', 'jfif'))]

class Error(Exception):
    """Base class for other exceptions"""
    pass

def convert_image(image_path, image_type):

    im = Image.open(image_path)
    im = im.convert('RGB')
    image_name = image_path.split('.')[0]
    print(f"This is the image name: {image_name}")

    if image_type == 'jpg' or image_type == 'png' or image_type == 'jfif':
        im.save(f"{image_name}.webp", 'webp')
    else:
        raise Error

    for image in images:
        if image.endswith('jpg'):
            convert_image(image, image_type='jpg')
        elif image.endswith('png'):
            convert_image(image, image_type='png')
        elif image.endswith('jfif'):
            convert_image(image, image_type='jfif')    
        else:
            raise Error

convert_image('C:\\Users\\Dani\\Desktop\\Webp', 'png')        

This is my script and directory

And this is the errors Which I get when I run the script How can I get rid of these permissions or what should I do? enter image description here

    runpy.run_path(target_as_str, run_name=compat.force_str("__main__"))

Test whether the filename is a file or a directory. If it's a directory, loop through the files in the directory and call the function recursively. If it's a file, convert it.

def convert_image(image_path, image_type):

    if image_type not in ('jpg', 'png', 'jfif'):
        raise Error

    if os.path.isdir(image_path):
        for file in glob.glob(os.path.join(image_path, '*.'+image_type)):
            convert_image(file, image_type)
        return
    
    im = Image.open(image_path)
    im = im.convert('RGB')
    image_name = image_path.split('.')[0]
    print(f"This is the image name: {image_name}")

    im.save(f"{image_name}.webp", 'webp')
