title: Why can't if statement be empty in python like in some other languages?
body: <p>Let's say I have some if statements:</p>
  
  <pre><code>thing = true
  if thing:
      #something i will decide later
  else:
      print ("well that thing is not true")
  </code></pre>
  
  <p>If I am just leaving something there for testing or want to have it there for structural purposes or maybe it just makes sense with the rest of the code (like an if statement for each letter, but "Z" is empty, and i might add it later).</p>
  
  <p>In Python, I absolutely CANNOT leave an if statement empty. Why is that? Is it something to do with the indentations and the getting confused? Is it because there are no brackets, so then somehow it will get messed up? I don't understand why I this is disallowed. Please explain. Thanks!</p>
