What's wrong in my python code?
<p>Can anyone tell me what's wrong in this code:</p>

<pre><code>#!/usr/local/bin/python

import os
import string, sys

a='sys.argv[1]'
b='sys.argv[2]'
os.system("scp a:/export/home/sample/backup.sql  b:/home/rushi/abc.sql")
</code></pre>

<p>it's giving the following error:</p>

<pre><code>ssh: a: node name or service name not known
</code></pre>
