title: Call Python script from bash with argument
body: <p>I know that I can run a python script from my bash script using the following:</p>
  
  <pre><code>python python_script.py
  </code></pre>
  
  <p>But what about if I wanted to pass a variable / argument to my python script from my bash script. How can I do that?</p>
  
  <p>Basically bash will work out a filename and then python will upload it, but I need to send the filename from bash to python when I call it.</p>
