A short one liner to quickly serve any folder via a http server.
Start the server
cd to the directory you want to serve.
Python 2.7
At the shell prompt enter python -m SimpleHTTPServer
Python 3
At the shell prompt enter python -m http.server
Access the files from your browser
When run the command will output the port which the server is available on.
You can optionally provide a port number e.g. python -m SimpleHTTPServer 8080 to set this yourself. You can only serve a single folder at each port.
Open your web browser and access http://localhost:PORT/
If you set the port number yourself access via http://localhost:8080 changing 8080 to the port number you picked.
