Well you open the file and create a writer but you don't write anything. You 
need this part

      [table] = soup.find_all("table")
      for row in table.find_all("tr"):
          writer.writerow(
              [td.string.strip() for td in row.find_all("td")]
          )

inside the with-suite, too. 

If you are interested in learning Python, you may put it into a function and 
invoke it twice, with the writer writing to stdout and the writer writing to 
the file.
