how to(can we ?) pass argument to .py script ?

[quiteblack at gmail.com]

howdy~

i wrote a .py file and it works fine, my goal is to pass argument to
that py file when it get executed, and accept that argument within py
file, eg. i prefer a command like below:

python test.py -t

and then, i may get "-t" within test.py for later use.

i have no ideas how to do and i'm really stuck, can anyone help ?
