os模块练习题

1、写一个删除日志的脚本，把三天前的日志并且为空的日志删除

 

我写的

import os,time
def ces(ces):
    time_tuple = time.strptime(ces, '%Y-%m-%d')
    time_stamp_nwo = time.mktime(time_tuple)
    return time_stamp_nwo

#三天前的
for cur_path,dirs,files in os.walk(r'C:Usersv-dongchunguangPycharmProjectsuntitledday5logs'):
    seven = int(time.time()) - 60 * 60 * 24 * 3
    for file in files:
       files=file.split('_')[1].split('.')[0]
       c=ces(files)
       cc=os.path.join(cur_path,file)#拼接路径
       ccs=os.path.abspath(cc)#不加找不到
       if c<seven or os.path.getsize(cc)==0:
           if time.strftime('%Y-%m-%d') in file:#如果当天文件在这里就不删除
               continue
           os.remove(cc)

标准的

import os
import time

day = 60 * 60 * 24 * 3

def str_to_timestamp(str_time,format='%Y-%m-%d'):
    time_tuple = time.strptime(str_time,format)
    return int(time.mktime(time_tuple))


def clean_log(path):
    if os.path.isdir(path):
        for cur_path,dirs,files in os.walk(path):
            for file in files:
                if file.endswith('.log'):

                    #apache_2020-09-04.log
                    #a.log
                    try:
                        file_time = file.split('.')[0].split('_')[-1]
                    except Exception as e:
                        print(e)
                        print('%s 不是标准的日志文件，不处理'%file)
                    else:
                        pass
                        file_time_stamp = str_to_timestamp(file_time)
                        ago_time_stamp = time.time() - day
                        file_abs_path = os.path.join(cur_path, file)
                        if file_time_stamp < ago_time_stamp or os.path.getsize(file_abs_path) == 0 :
                            # if time.strftime('%Y-%m-%d') in file:
                            #     continue
                            os.remove(file_abs_path)
    else:
        print('路径错误！')


clean_log('logs')
