title: Change Python interactive prompt ">>>"
body: <p>I recall reading, in the Python 3.5 docs, how to change the <code>&gt;&gt;&gt;</code> on the Python interactive prompt, such as how calling <code>help()</code> will change it to <code>help&gt;</code>.</p>
  <p>But for some reason, when I've gone back to try and remember, I just can't find the instructions to it. Does anyone know if this is possible?</p>
