python newbie question

[ken.carlino at gmail.com]

I am new to python, can you please tell me how can I convert my python
script into an executable on linux?
i.e. instead of typing 'python myscript.py abc', I just need to do
'myscript.py abc'?
and how can I get the input argument from my script , in my example,
how can I read 'abc'?

Thank you.
