title: Comma separated inputs instead of space separated inputs for argparse
body: <p>I'm using <code>argparse</code> to receive inputs from the command line to run my script.</p>
  
  <p>My current input string looks like this:</p>
  
  <pre><code>path&gt; python &lt;\filename\\&gt; -t T1 T2 T3 -f F1 F2
  </code></pre>
  
  <p>Is there a parameter in argparse such that instead of separating inputs by space, I can separate them by commas?</p>
  
  <p>In other words:</p>
  
  <pre><code>path&gt; python &lt;\filename\\&gt; -t T1,T2,T3 -f F1,F2
  </code></pre>
