like when you run your script demo.py  

because it relay helps with understanding dynamic webpages and how you use the same script to fetch different data based on a parameter :)

These are called command line arguments, and are used for programs run from the command line. Perl uses the built-in array @ARGV. Likewise, Python uses the array sys.argv. The names are a nod to C, where arguments are passed to the main function as parameters traditionally named argc & argv (though this is not a requirement, merely convention).
