We ran across this one in the OECD healthcare data. The country names had numbers appended, which served as footnotes in the original spreadsheet but looked dumb when we used them as index labels. The question is how to eliminate them. A short version of the country names is

`names = ['Australia 1', 'Canada 2', 'Chile 3', 'United States 1']`

Do each of these in a separate code cell:

1. Set `us = names[-1]` and call the `rsplit()` method on us. What do you get?
2. Consult the documentation for `rsplit` to split `us` into two pieces, the country name and the number 1. How would you extract just the country name?
3. Use a loop to strip the numbers from all of the elements of `names`.
4. Use a list comprehension to strip the numbers from all of the elements of `names`.
