[web2py] redirecting python console output to web browser page

[blackshirt]

i have a little programming with web2py, with import some library from
python-apt...
i want to show output from some command/function from that library to
the web page..
Output from that script showing on console, not showing on web page,
but only result on return value (True / false) send to web page..


Here some code from controller page

def update():

    apt_pkg.init()
    cache = apt.Cache()
    cache.update(apt.progress.TextFetchProgress())
    cache.open(None)

this successfully run, if we call this controller, but output show on
console not send to page..
How we solved this, i'm stuck here ?

Thanks for clue, advice, or reply's
