看过简明 python 教程的帮忙解答:第十章的写一个备份脚本文件， #!/usr/bin/env python # Filename: backup_ver1.py import sys import os import time # 1. The files and directories to be backed up are specified in a list. source=[r'C:\work1',r'D:\Work'] # If you are using Windows, use source=[r'C:\Documents',r'D:\Work'] or something like that # 2. The backup must be stored in a main backup directory target_dir=r'D:\yss' #Remember to change this to what you will be using # 3. The files are backed up into a zip file # 4. The name of the zip archive is the current date and time target=target_dir+time.strftime('%Y%m%d%H%M%S')+'.zip' # 5. We use the zip command (in Unix/Linux) to put the files in a zip archive zip_command="zip -qr '%s' %s" %(target,' '.join(source)) # Run the backup if os.system(zip_command)==0: print 'Successful backup to',target else: print 'Backup FAILED' 我运行后返回的是 Backup FAILED 什么原因照成的啊！
