title: Python: How do I write a dot over letters/variables, signifying the time derivative in physics?
body: <p>I am looking for a way to place a bold dot above letters/variables to signify the time derivative. Ideally for both Python itself, but mainly for matplotlib axes.</p>
  <p>I would expect something similar like:</p>
  <pre><code>print(u'1\u0305')
  </code></pre>
  <p>Although this is a very basic question, I cannot find anything, especially, because the term &quot;dot notation&quot; in Python is something completely different.</p>
  <p>Thank you in advance.</p>
