python+winrar 指令压缩文件

1 windows环境

2已安装winrar软件

3将winrar.exe拷贝到系统的system32目录下

4压缩的源文件D:/WORK

5目标文件位于D盘根目录下，名称为当前的时间日期.rar

6 附上winrar其他指令 http://www.docin.com/p-274023603.html&endPro=true

import os
import time

source = r'D:\work'

target_dir = r'D:\\'


target = target_dir + time.strftime('%Y%m%d%H%M%S')+'.rar'


rar_command = "winrar a {0} {1}".format(target, source)

if os.system(rar_command) ==0:
    print("成功")
else:
    print("失败")

优化方案一、

import os
import time

source = r'D:\work'
target_dir = r'D:\\'

today = target_dir + time.strftime('%Y%m%d')
now = time.strftime('%H%M%S')

if not os.path.exists(today):
    os.mkdir(today) # make directory
    print( 'Successfully created directory', today)
  
target = today + os.sep + now + '.rar'

rar_command = "winrar a {0} {1}".format(target, source)

if os.system(rar_command) ==0:
    print("成功")
else:
    print("失败")
