Pen Names

In this exercise, we have set up a spider class which, when finished, will retrieve the author names from a shortened version of the DataCamp course directory. The URL for the shortened version is stored in the variable url_short. Your job will be to create the list of extracted author names in the parse method of the spider.

Two things you should know:

You will be using the response object and the css method here.
The course author names are defined by the text within the paragraph p elements belonging to the class course-block__author-name

You can inspect the spider using the function inspect_spider() that we built for you -- it will print out the author names you find!

Note that this and the remaining exercises in this chapter may take some time to load.
