如何删除文件夹中所有的全黑图片？

import os
from PIL import Image

def delete_black_images(folder_path):
    for filename in os.listdir(folder_path):
        file_path = os.path.join(folder_path, filename)
        if os.path.isfile(file_path):
            # 判断文件是否为图片
            if filename.lower().endswith(('.jpg', '.jpeg', '.png', '.gif')):
                try:
                    image = Image.open(file_path)
                    pixels = image.load()
                    is_black = True
                    # 遍历像素点，判断是否全黑
                    for x in range(image.width):
                        for y in range(image.height):
                            r, g, b = pixels[x, y]
                            if r != 0 or g != 0 or b != 0:
                                is_black = False
                                break
                        if not is_black:
                            break
                    # 删除全黑图片
                    if is_black:
                        os.remove(file_path)
                        print("Deleted:", file_path)
                except Exception as e:
                    print("Error processing:", file_path)
                    print(e)

# 调用函数删除文件夹中所有的全黑图片
delete_black_images("文件夹路径")
