I don't know about the htmllib module, but if a function takes
a stream (a.k.a. file object), and you want to store the value
in a variable, you van use cStringIO.

>>> import cStringIO
>>> f = cStringIO.StringIO()
>>> f.write("aaa")
>>> f.write("bbb")
>>> print f
<StringO object at 80c57b0>
>>> print f.getvalue()
aaabbb
>>> f.seek(3, 0)
>>> print f.read()
bbb

See also:
http://www.python.org/doc/current/lib/module-StringIO.html

This is the documentation for the StringIO module; the cStringIO
module is identical, except that it's written in C: It's 1000 times
faster, but you can't subclass the StringIO class.

regards,
Gerrit.
