I strongly suspect you're new to python and even to programming too.

You understand that this loop will execute _at most_ once ? And that
it may never execute at all - which seems to be your problem here -,
resulting in neither of the explicit "return" statement being
executed, so the function implicitely returns None ?

Hint : if you're using the builtin dev server (this is what you're
doing, right ?), then add a couple print statements here and there to
tell where you are and what values you have, ie:
print "before loop, 'log' is '%s', u_name is '%s' '" %
(repr(log), u_name)
for x in log:
print "in loop, x is '%s', x[1] is '%s'" % (x, x[1])
if u_name ==x[1]:
print "match -- returning 'index'"
return render_to_response('index.html',{"log":log})
else:
print "don't match - returning 'wrong' "
return render_to_response('wrong.html')
# if we end up here then 'log' was an empty iterable
print "oops, 'log' was empty, didn't enter the loop, implicitely
returning None"
This should help you finding out what happens.
