You will need to change your directory to the directory that contains your exercise script, probably by doing "cd /path/to/exercise/directory". If you're on Windows it's the same idea, you run the "cmd" program, but you would have to specify the full path to the python interpreter instead of just "python", or follow the directions that have been offered for fixing Windows.

You didn't provide any arguments to the script.
=C2=A0
in the book the author says that i should run the program like this:

$ python ex13.py first 2nd 3rd
The script is called: ex13.py
Your first variable is: first
Your second variable is: 2nd
Your third variable is: 3rd
but how ca= n i do that?? what are the steps? where should i go?

You need to open a comma= nd line terminal and type the first line (without the dollar sign). You wil= l need to change your directory to the directory that contains your exercis= e script, probably by doing "cd /path/to/exercise/directory". If = you're on Windows it's the same idea, you run the "cmd" p= rogram, but you would have to specify the full path to the python interpret= er instead of just "python", or follow the directions that have b= een offered for fixing Windows.
