Actually, what the traceback says is that
1/ attrs is a list object
2/ list objects have no attribute named iteritems

If you assumed it was a dict, then it's probably time to re-read 
HTMLParser's doc. Else if you assumed list had an iteritems method, then 
it's probably time to re-read the Python's tutorial !-)

IIRC, HTMLParser represents attributes as a list of (attrname, value) 
pairs. If so (please check it out), your method should be rewritten as

     return ' %s' % (' '.join(('%s="%s"') % attr for attr in attrs)


As a side note: __double_leading_undescores is probably a bit extrem. 
The convention for implementation attributes is _single_leading_underscore.
