-# You don't have to do things with the ScraperWiki and lxml libraries.
-# You can use whatever libraries you want: https://morph.io/documentation/python
-# All that matters is that your final data is written to an SQLite database
-# called "data.sqlite" in the current working directory which has at least a table
-# called "data".

+# 1. Parse the raw HTML to get the interesting bits - the part inside <td> tags.
+# -- UNCOMMENT THE 6 LINES BELOW (i.e. delete the # at the start of the lines)
+# -- CLICK THE 'RUN' BUTTON BELOW
+# Check the 'Console' tab again, and you'll see how we're extracting 
+# the HTML that was inside <td></td> tags.
+# We use lxml, which is a Python library especially for parsing html.
+# -----------------------------------------------------------------------------
+
+import lxml.html
+root = lxml.html.fromstring(html) # turn our HTML into an lxml object
+tds = root.cssselect('td') # get all the <td> tags
+for td in tds:
+   print lxml.html.tostring(td) # the full HTML tag
+   print td.text                # just the text inside the HTML tag
+
+# -----------------------------------------------------------------------------
+# 2. Save the data in the ScraperWiki datastore.
+# -- UNCOMMENT THE THREE LINES BELOW
+# -- CLICK THE 'RUN' BUTTON BELOW
+# Check the 'Data' tab - here you'll see the data saved in the ScraperWiki store. 
+# -----------------------------------------------------------------------------
+
+for td in tds:
+    record = { "td" : td.text } # column name and value
+    scraperwiki.sqlite.save(["td"], record) # save the records one by one
