 | Python offers two modules for command-line argument parsing: getopt and optparse |
| These accept short options (-m) and long options (--mass) |
| getopt examines the command line and returns pairs of options and values ((--mass, 2.3)) |
| optparse is a bit more comprehensive to use and makes the command-line options available as attributes in an object |
| In this introductory example we rely on manual parsing since this exemplifies basic Python programming |
