python3-natsort binary package in Ubuntu Focal amd64

 natsort lets you apply natural sorting to your sequences easily, for example:
 .
  >>> from natsort import natsorted
  >>> a = ['a2', 'a9', 'a1', 'a4', 'a10']
  >>> data = [['a1', 'a5'], ['a1', 'a40'], ['a10', 'a1'], ['a2', 'a5']]
  >>> natsorted(a)
  ['a1', 'a2', 'a4', 'a9', 'a10'
  >>> natsorted(data)
  [['a1', 'a5'], ['a1', 'a40'], ['a2', 'a5'], ['a10', 'a1']]
 .
 natsort identifies the numbers and sorts them separately from strings.
 .
 natsort comes with a shell script to use natural sorting in shell scripts. You
 can also execute natsort from the command line with Python -m natsort.
 .
 There exists another natural sorting package for Python called
 python-naturalsort. You may prefer that package if you wish to only sort
 version numbers.
 .
 This is the Python 3 version of the package.
