使用Python在Windows下调用Winrar备份文件

import os
import time

source='C:\\Linda\\Test\\Python\\source'
target_dir='C:\\Linda\\Test\\Python\\backup\\'

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

print(target)

rar_command = "winrar a %s %s"%(target,source)
print (rar_command)

if os.system(rar_command)==0:
    print ('Succeed to backup to', target)
else:
    print ("Backup FAILED")
