+The :mod:`argparse` module provides a mechanism to process command line arguments.
+It should always be preferred over directly processing ``sys.argv`` manually.
+
+Take, for example, the below snippet of code::
+
+   >>> import argparse
+   >>> from getpass import getuser
+   >>> parser = argparse.ArgumentParser(description='An argparse example.')
+   >>> parser.add_argument('name', nargs='?', default=getuser(), help='The name of someone to greet.')
+   >>> parser.add_argument('--verbose', '-v', action='count')
+   >>> args = parser.parse_args()
+   >>> greeting = ["Hi", "Hello", "Greetings! its very nice to meet you"][args.verbose % 3]
+   >>> print(f'{greeting}, {args.name}')
+   >>> if not args.verbose:
+   >>>     print('Try running this again with multiple "-v" flags!')
