title: Python: What is a header?
body: <p>I'm new to Python and programming in general. I am taking a module at university which requires me to write some fairly basic programs in Python. However, I got this feedback on my last assignment:</p>
  
  <blockquote>
    <p>There should be a header block containing the file name, author name, date created, date modified and python version</p>
  </blockquote>
  
  <p>What is a header block? Is it just comments at the top of your code or is it be something which prints when the program runs? Or something else?</p>
