Hints

General

1. Explain wine colors

  • You need to write the information given in the table as a keyword list.
  • Take a look at some examples of how to define a keyword list.

2. Get all wines of a given color

3. Get all wines of a given color bottled in a given year

  • There is a built-in function for getting a single value for a given key.
  • You do not need to implement the filtering of bottles on your own. You just need to conditionally use the already-implemented filter_by_year/2 function.

  • There is a built-in function for getting a single value for a given key.
  • You do not need to implement the filtering of bottles on your own. You just need to conditionally use the already-implemented filter_by_country/2 function.
