I agree, but than the exception should have a better message:

$ python escape.py
Traceback (most recent call last):
   File "escape.py", line 3, in ?
     cgi.escape(2)
   File "/usr/lib/python2.2/cgi.py", line 1024, in escape
     s = s.replace("&", "&") # Must be done first!
AttributeError: 'int' object has no attribute 'replace'


A exception with a message like:
"Argument must be a string"

would be better
