That's exactly where I checked. I don't understand what the documentation says..
More specifically I don't understand this
"sys.argv¶

The list of command line arguments passed to a Python script. argv[0] is the script name (it is operating system dependent whether this is a full pathname or not). If the command was executed using the -c command line option to the interpreter, argv[0] is set to the string '-c'. If no script name was passed to the Python interpreter, argv[0] is the empty string."

Maybe a little example will help ...
python Syntax (Toggle Plain Text) 
  1. import sys
  2.  
  3. args = sys.argv
  4.  
  5. print(args)
  6. print( "Source  file: %s" % args[0] )
  7. # use any of these arguments in your code
  8. print( "Argument one: %s" % args[1] )
  9. print( "Argument two: %s" % args[2] )
  10.  
  11.  
  12. """
  13. my output after saving this code as sysargs1.py and 
  14. entering a few arguments on the command line -->
  15. ['D:/Python25/Bull/sysargs1.py', 'myarg1', 'myarg2']
  16. Source  file: D:/Python25/Bull/sysargs1.py
  17. Argument one: myarg1
  18. Argument two: myarg2
  19. """
May 'the Google' be with you!

So for the last two to have values, is it compulsory for the program to be run via command line?

You can run it with module subprocess as well
python Syntax (Toggle Plain Text) 
  1. import subprocess
  2. child = subprocess.Popen("sysargs1.py myarg1 myrag2", shell=True)

It allows your program to launch other programs and communicate with them.
