title: How to get tomorrow's date in isoformat using datetime
body: <p>I'm trying to get tomorrow's date using the datetime module, just as you can get today's date. As far as i know, there isn't a simple function that returns the next day's date, but from googling i found that you can use timedelta to increment days.
  However, i need the date to be in isoformat, just as today's date.
  This is what i currently have:</p>
  <pre><code>now = datetime.datetime.utcnow().isoformat() + 'Z' 
  tomorrow = now + str(datetime.timedelta(days=1))
  print(now)
  print(tomorrow)
  </code></pre>
  <p>However, this returns the following for now and today respectively:</p>
  <pre><code>2021-04-18T11:18:30.363421Z
  2021-04-18T11:18:30.363421Z1 day, 0:00:00
  </code></pre>
  <p>I need the next day's date to be the same format (isoformat) as today's date. Anyone know how to do this properly?</p>
