You can start a local web server to try your web site with one single command. Open Terminal, navigate to the folder that you want to use as a local server and type one of the following commands:
To open with browser typing: http://localhost:8000
python -m SimpleHTTPServer
If you don’t want to write the port you can specify it before.
Then you have to type in browser: http://localhost
sudo python -m SimpleHTTPServer 80
Note: You can specify any port that you need (for example, port 8080).
