Rating the weather conditions

In the previous exercise, you counted the number of bad weather conditions each day. In this exercise, you'll use the counts to create a rating system for the weather.

The counts range from 0 to 9, and should be converted to ratings as follows:

Convert 0 to 'good'
Convert 1 through 4 to 'bad'
Convert 5 through 9 to 'worse'

Count the unique values in the bad_conditions column and sort the index. (This has been done for you.)
Create a dictionary called mapping that maps the bad_conditions integers to strings as specified above.
Convert the bad_conditions integers to strings using the mapping and store the results in a new column called rating.
Count the unique values in rating to verify that the integers were properly converted to strings.
