30. Sorting by multiple columns
Summary

Instruction

Good! If you want to sort by multiple columns, it’s also very easy:

hospitals = hospitals.sort_values(by=['Hospital overall rating','Hospital Name'])

The code above will first sort all rows by Hospital overall rating. Then, for rows with the same value in that column, it will sort by Hospital Name.

Exercise

Sort all countries in eu_states by Accession Year, and then by GDP.

Stuck? Here's a hint!

For the by= argument, use the following value:

['Accession Year', 'GDP']
