body: <p>Do Python have logical inversion mark like exclamation mark in Java?</p>
  
  <p>In Java, </p>
  
  <p><code>bool myBool = true; 
   System.out.println(!myBool);</code> should give us the output "false".</p>
  
  <p>But what about Python? In Python, is there any mark?</p>
  
  <p>edit: I know the keyword "not". I am asking for a mark.</p>
