Import argparse. Create an argument parser by instantiating ArgumentParser. Add arguments and options to the parser using the .add_argument() method. Call .parse_args() on the parser to get the Namespace of arguments. As an example, you can use argparse to improve your ls_argv.py script....
Strings are still str type by default but they now mean unicode code points instead — we carry what we see. If we want to store these str type strings in files we use bytes type instead. Default encoding is UTF-8 instead of ASCII. Perfect!
