删除所有超过30天的文件，基于文件名作为日期

import os
import datetime

def delete_old_files(directory):
    files = os.listdir(directory)
    current_date = datetime.datetime.now()

    for file in files:
        file_path = os.path.join(directory, file)
        if os.path.isfile(file_path):
            file_name = os.path.splitext(file)[0]
            try:
                file_date = datetime.datetime.strptime(file_name, "%Y%m%d")
                time_diff = current_date - file_date
                if time_diff.days > 30:
                    os.remove(file_path)
                    print(f"Deleted file: {file}")
            except ValueError:
                continue

# 调用函数并传入指定目录
