Why are only the first and last items of my list being written to file?
<p>I've written my very first webscraper, and I am now attempting to write the data to excel files. </p>

<p>This is the relevant part of my program: </p>

<pre><code>with xlsxwriter.Workbook('test 2.xlsx') as workbook:
    worksheet = workbook.add_worksheet("Doctissimo's diabetes sub-forum")

    row = 0
    col = 0

    for time, handle, post, URL in list(zip(time_stamps, handles, post_contents, URLs)):

       print(time, handle, URL)

       worksheet.write(row, col, time)
       worksheet.write(row, col+1, handle)
       worksheet.write(row, col+2, post)
       worksheet.write(row, col+3, URL)

       row = +1
</code></pre>

<p>My problem is that only the first and last item of each list (time_stamps, handles, post_contents, URLs) are being written to file.</p>

<p>The zipped lists are of equal length (I checked using <code>print(len(list))</code>, and the other items are not empty (also checked using <code>print</code>). What have I done wrong?</p>
