Trying to load up the web interface, all programs on that link are installed. I'm stuck where to write the command to access the wallet tools in the browser.

How to run it

   '' Download it there: https://github.com/jackjack-jj/pywallet
    Run './pywallet.py –web' then open 'http://localhost:8989' in your browser''

Where do I type  "Run './pywallet.py –web'" ?
