Question

Given a Python string like this:

location_in = 'London, Greater London, England, United Kingdom'

I would like to convert it into a list like this:

location_out = ['London, Greater London, England, United Kingdom',
                'Greater London, England, United Kingdom',
                'England, United Kingdom',
                'United Kingdom']

In other words, given a comma separated string (location_in), I would like to copy it to a list (location_out) and gradually break it down by removing the first word/phrase each time.

I’m a Python newbie. Any ideas on a good way to write this? Thanks.

Answer 1

location_in  = 'London, Greater London, England, United Kingdom'
locations    = location_in.split(', ')
location_out = [', '.join(locations[n:]) for n in range(len(locations))]
