python批量修改png后缀为jpg

在Python中，你可以使用`os`模块配合图像处理库如`PIL`（Python Imaging Library）来批量修改文件后缀名。以下是一个简单的步骤示例：

import os
from PIL import Image

# 确定图片所在的目录
directory = '/path/to/your/images'

# 遍历指定目录下的所有png文件
for filename in os.listdir(directory):
    if filename.endswith('.png'):  # 检查是否为png文件
        old_path = os.path.join(directory, filename)  # 获取旧路径
        new_filename = filename.replace('.png', '.jpg')  # 修改后缀名为.jpg
        new_path = os.path.join(directory, new_filename)  # 获取新路径

        try:
            with Image.open(old_path) as img:
                img.save(new_path)  # 将PNG文件转换并保存为JPG
                print(f"Converted {old_path} to {new_path}")
        except Exception as e:
            print(f"Error processing {old_path}: {e}")
