It's not at all clear what you're trying to do. The line above creates a dict
with a single entry whose key is x, and whose value is a list with x as a
member. That doesn't seem very useful.
If you want a variable number of forms to be displayed, try creating a list of
forms, and passing the list to your view in a dict as usual. The code that
JmiXIII gave is a good example:
def listform():
listf=[]
thing = [one two three]
for x in thing:
form=FORM(':', INPUT(_name="name"))
listf.append(form)
return dict(listf=listf)
In your view, you'll have to loop through the list and output each form.
One problem with the code above is that you'll need to give each form a unique
name. See "Multiple forms per page" in the manual, Chapter 7.
