为什么我的Python程序无法正常运行？ 它可以运行，但没有得到我想要的结果

Question

The function of the program is to compress two folders and then save them to one folder. The program can run but I get an error message exactly as follows:

C:\Python34\python.exe D:/Python/backup_ver1.py
'zip' �����ڲ����ⲿ���Ҳ���ǿ����еij���
���������ļ���

Failed backup

Yes, it's just as you see. I can't get more information from that.

The code is as follow:

import os
import time
source = ['E:\\source1','E:\\source2']
target_dir = 'E:\\target'
target = target_dir + os.sep + time.strftime("%Y%m%d%H%M%S") +'.zip'
zip_command = 'zip -qr {0} {1}'.format(target,' '.join(source))

if os.system(zip_command) == 0:
    print("Successful bakup to",target)
else:
    print("Failed backup")

I have "source1", "source2" and "target" in my computer.

I use 7zip on my system, so my syntax is a little different than yours. Try this:

import os
import time
source = ['d:\\source1','d:\\source2']
target_dir = 'd:\\target'
target = target_dir + os.sep + time.strftime("%Y%m%d%H%M%S") +'.zip'
zip_command = '"C:\\Program Files\\7-Zip\\7z.exe" a {0} {1}'.format(target,' '.join(source))
if os.system(zip_command) == 0:
    print("Successful bakup to",target)
else:
    print("Failed backup")
