title: os.system command to call shell script with arguments
body: <p>I am writing a python script which uses <code>os.system</code> command to call a shell script.I need help understanding how I can pass the arguments to the shell script? Below is what I am trying..but it wouldn't work.</p>
  
  <pre><code>os.system('./script.sh arg1 arg2 arg3')
  </code></pre>
  
  <p>I do not want to use <code>subprocess</code> for calling the shell script. Any help is appreciated.</p>
