I tried the following (from the dominate package README) with Python 3.7.3 and dominate==2.3.5 in a virtual environment under OSX Mojave:

    _html = html()
    _head, _body = _html.add(head(title('Whatever')), body())
    print(_html)
    names = ['header', 'content', 'footer']
    header, content, footer = _body.add(div(id=name) for name in names)
    print(_html)

and got the following output:

<html>
  <head>
    <title>Whatever</title>
  </head>
  <body></body>
</html>
Traceback (most recent call last):
  File "scripts/alt_index.py", line 54, in <module>
    OPTIONAL_ARGUMENTS, POSITIONAL_ARGUMENTS, DEFAULT_LOG_LEVEL))
  File "scripts/alt_index.py", line 44, in main
    header, content, footer = _body.add(div(id=name) for name in names)
ValueError: not enough values to unpack (expected 3, got 0)

Fixed. This was due to returning an exhausted generator
