modifying parts of a urlparse.SplitResult

I can successfully parse my URLs. However, I'd like to modify a part
then reassemble them. However, like tuples, the parts appear to be
unmodifiable
>>> URL = 'http://foo/path1/path2/?fragment=foo'
>>> import urlparse
>>> u = urlparse.urlparse(URL)
>>> u
ParseResult(scheme='http', netloc='foo', path='/path1/path2/',
params='', query='fragment=foo', fragment='')
>>> u.query
'fragment=foo'
>>> u.query = 'blah=baz'
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: can't set attribute
The best I've been able to come up with is
>>> u = urlparse.urlsplit(URL)
>>> lst = list(u) # can't manipulate the tuple directly
>>> lst[3] = "bar=baz" # 3 = query-string index
>>> urlparse.urlunsplit(lst)
'http://foo/path1/path2/?bar=baz'
It takes knowing that "3" is the magic index (documented, but not
given some named-constant in urlparse) for the query-string. Is
there some better, clearer, or more Pythonic way to do this?
