keep in mind, that production servers have buffering. For example, if you 
are using  nginx you should turn off 'proxy_buffering' for the 'streamer' 
location.

 If the controller takes 10 minutes , the view is blank for 10
 minutes and that is not a good thing for the user.

 How can i have the controller to send the data to the view and the
 view to display data as it is being calculated from the controller?
 Is it possible in a simple manner?

I don't have PY3, so can't test. If it's bytes, then it 's already encoded 
and all should work OK. Try ...xml().decode().encode('utf-8')  or try to 
yield something simple  - just 'hello'

 Hello i have a controller that scans a lot of databases searching for

 If the controller takes 10 minutes , the view is blank for 10 minutes
 and that is not a good thing for the user.

 How can i have the controller to send the data to the view and the view
 to display data as it is being calculated from the controller?
 Is it possible in a simple manner?

For that I would use a stream.  There are a couple of examples that have 
popped up here on occasion, although I can't at the moment link to them.  
Which stream module you use may depend on whether your results are 
text/html, or binary data (like a video).  I think I have an example at 
home for that I used for returning a jpg, but my glasses aren't good enough 
to see it from here.

One option would be to use the web2py scheduler to run the calculations as 
a background task. As results are generated, they could temporarily be 
stored in a special database table. From the browser, you can then make 
periodic Ajax requests (perhaps every few seconds) to check for new results 
in the special table.

As an alternative to the Ajax polling, you could use server push (e.g., 
Websockets or Server Sent Events) to push results to the browser. If you 
want to take that approach, consider external pubsub servers such as Nchan 
 or Centrifugo 
, or realtime services such as 
Realtime.co, Ably, Pusher, Pubnub, or Firebase.

but the idea is to get some of the data as it is being calculated in the
controller.
