title: How to print math symbols in python?
body: <p>I would like to print math in python with print(), as it is possible to do in plot's label with matplotlib (see this link for all the math you can write with matplotlib <a href="https://matplotlib.org/tutorials/text/mathtext.html" rel="nofollow noreferrer">https://matplotlib.org/tutorials/text/mathtext.html</a> )
  Is that even possible ?
  I tried the following (as in matplotlib):</p>
  
  <pre><code>print(r'$\Delta v$:', delta)
  </code></pre>
  
  <p>to print a greek delta for example, but it doesn't work (as it's not a matplotlib function), it shows : <code>$\Delta v$: delta</code></p>
