title: How do you split full name to first and last names if some people only put their first name in the list? Using OpenPyxl
body: <p>#What I have so far that doesn't work as I get the error: ValueError: not enough values to unpack (expected 2, got 1).</p>
  <pre><code>for cell in ws[fullname_column][1:]:
      firstname, lastname = cell.value.split()
      ws.cell(row=cell.row, column=firstname_column).value = firstname
      ws.cell(row=cell.row, column=lastname_column).value = lastname
  </code></pre>
