linux 通过python 命令定时删除文件，不通过crontab

import os
import time

log_dir = "/var/log/"


def delete_expired_logs():
    current_time = time.localtime()
    print(current_time.tm_hour)
    if current_time.tm_hour == 12 and current_time.tm_min == 30:
        print('xxxxxxxxxx')
        for filename in os.listdir(log_dir):
            print(filename ,'filename')
            print(time.time())
            if filename.startswith('messages-202') or filename.startswith('secure-202')  :
                print(filename)
                file_path = os.path.join(log_dir, filename)
                os.remove(file_path)
                print("22")
                with open('D:\sdm\X.txt', 'a') as file:
                    file.write(  T + ' ' +filename + '        被删除,删除脚本存放在了 /var/log目录下了，通过后台nohup python del_log 命令运行的.' + '\n')

while True:
    delete_expired_logs()
    time.sleep(10)
