"The Fields of Saskatchewan" page

• How is the original problem reduced to finding the overlap? Not very important for here, but would be good to know how to explain/if someone asks
• In cell where show_fields is defined, the last line (call to show_fields) is missing a space between arguments
• After first plot: punctuation could be improved in a few places, sentences broken up strangely (eg "we can see that the area of overlap, is the same..." should not have a comma)
• Definition of overlap: lots of spaces missing for PEP8
• Using our tests: Would it be better to split this page in two different ones? One where we show how we decide which cases to test, and another in which we discuss how to run the tests (assertions vs running manually (and the rest of the page), leading into testing frameworks)

Start with the “The Fields of Saskatchewan” page and review the cell defining show_fields, the overlap definition, the text after the first plot, and the testing section. Check the missing spacing, PEP8 formatting, punctuation, and explanation of how the original problem becomes an overlap problem. Done means the page reads clearly and the proposed testing content is organized appropriately.
