Accessing command-line arguments

• All command-line arguments are available in sys.argv
• sys.argv[0] is the program
• sys.argv[1:] holds the command-line arguments
• Method 1: fixed sequence of parameters on the command line
• Method 2: --option value pairs on the command line (with default values)
