title: How to include a dynamic date in a string
body: <p>I'm trying to write a daily csv file but would like the title of the csv file to specify today's date.</p>
  <p>It seems to be failing every time but I'm sure there's an easy way to do this..?
  Hopefully this isn't a duplicate but can't seem to find another question similar.</p>
  <p>At the minute I've just tried this;</p>
  <pre><code>from datetime import date
  
  morningupdate.to_csv('morningupdate' + '_' + date.today() '.csv')
  
  </code></pre>
  <p>My brain is completely broken with this, any help much appreciated!</p>
