title: Handling arbitrary number of command line arguments in python
body: <p>I am trying to have my script be able to take in an arbitrary number of file names as command line arguments. In Unix, it is possible to use the '*' key to represent any character. For example, </p>
  
  <pre><code>ls blah*.txt 
  </code></pre>
  
  <p>will list every file with blah at the beginning and txt at the end. </p>
  
  <p>I need something like this for my python script. </p>
  
  <pre><code>python myscript.py blah*.txt
  </code></pre>
  
  <p>Is this possible? and if it is, how can it be done?</p>
