解决方案

当我们基本完成程序的设计,我们就可以编写代码了,它是对我们的解决方案的实施

版本一

例10.1 备份脚本——版本一

#!/usr/bin/python
# Filename: backup_ver1.py


import os
import time

# 1. The files and directories to be backed up are specified in a list.
source = ['/home/swaroop/byte''/home/swaroop/bin']
# 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 = '/mnt/e/backup/' # 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'

(源文件:code/backup_ver1.py)

输出

$ python backup_ver1.py
Successful backup to /mnt/e/backup/20041208073244.zip

现在,我们已经处于测试环节了,在这个环节,我们测试我们的程序是否正确工作。如果它与我们所期望的不一样,我们就得调试我们的程序,即消除程序中的 瑕疵 (错误)。
