[mod_python] req.form question

It didn't; whether the value is an object or a list depends on the form 
submission contents.

 From http://www.python.org/doc/2.2.3/lib/node297.html:

If the submitted form data contains more than one field with the same 
name, the object retrieved by "form[key]" is not a FieldStorage or 
MiniFieldStorage instance but a list of such instances. Similarly, in 
this situation, "form.getvalue(key)" would return a list of strings. If 
you expect this possibility (when your HTML form contains multiple 
fields with the same name), use the isinstance() built-in function to 
determine whether you have a single instance or a list of instances. For 
example, this code concatenates any number of username fields, separated 
by commas:


value = form.getvalue("username", "")
if isinstance(value, list):
     # Multiple username fields specified
     usernames = ",".join(value)
else:
     # Single or no username field specified
     usernames = value
