import os from datetime import datetime, timedelta import time delta = timedelta(days=2) now = datetime.now() delete_time = now - delta path = '/home/tomcat/tomcat-8.5.57-Portal/logs/backup' while True: for dirpath, dirnames, filenames in os.walk(path): for dirname in dirnames: if dirname[-8:].isdigit(): dir_time = datetime.strptime(dirname[-8:], '%Y%m%d') if dir_time < delete_time: for filename in os.listdir(os.path.join(dirpath, dirname)): os.remove(os.path.join(dirpath, dirname, filename)) os.rmdir(os.path.join(dirpath, dirname)) print('clean backup log')怎么结束循环

可以使用 `break` 关键字来结束循环。将 `while True` 改为一个条件语句，当满足条件时就跳出循环，例如：

import os
from datetime import datetime, timedelta

delta = timedelta(days=2)
now = datetime.now()
delete_time = now - delta
path = '/home/tomcat/tomcat-8.5.57-Portal/logs/backup'

while condition:
    for dirpath, dirnames, filenames in os.walk(path):
        for dirname in dirnames:
            if dirname[-8:].isdigit():
                dir_time = datetime.strptime(dirname[-8:], '%Y%m%d')
                if dir_time < delete_time:
                    for filename in os.listdir(os.path.join(dirpath, dirname)):
                        os.remove(os.path.join(dirpath, dirname, filename))
                    os.rmdir(os.path.join(dirpath, dirname))
    print('clean backup log')
    break  # 跳出循环

你需要将 `condition` 替换为跳出循环的条件。
