I wanted to make my website running Python 3 which is more new and bette:)

i treid to execute metrites.py via my jailed shell, please take a look if i'am not tiring you and maybe you can see if there is nothign wrong because i dont see nayhting.

The gethostbyaddr at the end its because the script run in cmd instead of in a browser.
Please help, its alkmost ready to run correctly!
