转换文件名的日期格式

import os
import re
from datetime import datetime

def convert_date_format(filename):
    # 匹配 MM/DD/YYYY 格式的日期
    match = re.search(r'(\d{2})/(\d{2})/(\d{4})', filename)
    if match:
        month, day, year = match.groups()
        new_date = f"{year}-{month}-{day}"
        new_filename = filename.replace(match.group(0), new_date)
        return new_filename
    return filename

def rename_files_in_directory(directory):
    for filename in os.listdir(directory):
        new_filename = convert_date_format(filename)
        if new_filename != filename:
            old_path = os.path.join(directory, filename)
            new_path = os.path.join(directory, new_filename)
            os.rename(old_path, new_path)
            print(f"Renamed '{filename}' to '{new_filename}'")

# 使用示例
directory_path = '/path/to/your/directory'
rename_files_in_directory(directory_path)
