Unless the html API has changed radically since Python 3.2a, I believe 
you are mistaken.

[steve at sylar ~]$ python3.2
Python 3.2a1 (r32a1:83318, Aug 12 2010, 02:17:22)

Type "help", "copyright", "credits" or "license" for more information.
>>> import html
>>> help(html)

which gives me the following information:

Help on package html:

    html - # This directory is a Python package.




So html is not a module, but a package that includes two sub-modules, 
entities and parser. I see no sign of anything called "escape" in either 
the top level html package, or either of the sub-modules, and the word 
"escape" only appears twice in the whole package, both times as 

[steve at sylar ~]$ cd /usr/local/lib/python3.2/html/
[steve at sylar html]$ ls  __pycache__
[steve at sylar html]$ grep -i escape *.py                attrvalue = self.unescape(attrvalue)    def unescape(self, s):

So I don't know what you are looking at, but I don't believe it is the 
standard html package in the Python standard library. Perhaps you have 
accidentally shadowed it with your own html module? Try this:

>>> import html
>>> html.__file__
