备份脚本问题

这个问题困扰了好几天，网上各种招资料还是不成功，求好心人帮助。谢谢！！

1. #!/usr/bin/python
   
2. # Filename: backup_ver1.py
   
3. 
   
4. import os
   
5. import time
   
6. 
   
7. # 1. The files and directories to be backed up are specified in a list
   
8. source = ['E:\\aaaa']
   
9. # If you are using windows ,use source = [r'C:\Documents',r'D:\Work'] or something like that
   
10. 
    
11. # 2. The backup must be stored in a main backup directory
    
12. target_dir = 'E:\\cccc\\' # Remember to change this to what you will be using
    
13. 
    
14. # 3. The files are backed up into a zip file.
    
15. # 4. The name of the zip archive is the current date and time
    
16. target = target_dir + time.strftime('%Y%m%d%H%M%S') + '.zip'
    
17. 
    
18. # 5. We use the zip command (in Unix/Linux) to put the files in a zip crchive
    
19. zip_command = "winrar a '%s' %s" % (target,''.join(source))
    
20. # Run the backup
    
21. if os.system(zip_command) == 0:
    
22.     print 'Successful backup to',target
    
23. else:
    
24.     print 'Backup FAILED'

你哪里存在问题，光光是把代码贴过来，但是不知道你哪里出问题了，希望你描述清楚

1. zip_command = "winrar a %s %s" % (target,''.join(source))

把那个单引号去掉就行了
