Solution is simple: Stop setting class variables in web development! :)
Web requests are stateless, it's mean you never know what's happen between requests - between setting class variable and redirect.
Use database to store temporary data with user login/name (or use hashing/random for security) or send values by parameters (hidden or after '?') to other html page.
Using database is better, if you don't want this then send values (hidden in html) over http. Here is one version of solution (without database):
1.Use normal html form and write handler for this form - question page.
2.In handler write get method like this:
def post(self, some_parameters):
...
self.render('homepage.html', {'ans_no': ans_no,\
'uans_no': uans_no ...})
3.homepage.html have to be template for showing results
