This keeps coming up. Note, it's actually in the book:

Notice that helper attributes are passed as keyword arguments to the
helper. In some cases, however, attribute names include special characters
that are not allowed in Python identifiers (e.g., hyphens) and therefore
cannot be used as keyword argument names. For example:
1.
DIV('text', _data-role='collapsible')
will not work because "_data-role" includes a hyphen, which will produce a
Python syntax error.
In such cases, you can instead pass the attributes as a dictionary and make
use of Python's ** function arguments notation, which map a dictionary of
(key:value) pairs into a set of keyword arguments:
1.
2.
>>> print DIV('text', **{'_data-role': 'collapsible'})
<div data-role="collapsible">text</div>
