from jcvi.apps.base import OptionParser # create an OptionParser object parser = OptionParser("script_name", "Description of script") # add command-line options parser.add_option("-a", "--arg1", dest="arg1", help="option1 help message") parser.add_option("-b", "--arg2", dest="arg2", help="option2 help message") # parse the command-line arguments (options, args) = parser.parse_args() # access the options and arguments print("Option 1 value: ", options.arg1) print("Option 2 value: ", options.arg2) print("Argument values: ", args)In this code example, we create an `OptionParser` object from `jcvi.apps.base` and add two command-line options `-a` and `-b`. Then, we parse the command-line arguments using the `parse_args()` function and store them in `options` and `args`. Finally, we print out the values of the options and arguments. Thus, the library `jcvi` provides the package `jcvi.apps.base` which contains the module `OptionParser` that helps with parsing command-line arguments.
