The solutions to the workshop can be found here.
They follow the convention used in the workshop.
In the case of the script 03_country-subset.py you will find also a 03_country-subset-forTest
the first one is the one you are given at the beginning and the second one (forTest) is the
modified version for the testing sections.
The exploratory notebook also has two versions: the original notebook and a second version which includes some tests inside the notebook.
You can also find here the environment.yml and .travis.yml files for the Continuous Integration sections
