It's nice to see the newcomer friendly tag being encouraged :thumbsup:

I'm submitting a PR for a doc change (I'd appreciate a review :D).

I've replaced any mention of getopt in the tutorial section with the argparse module. Additionally I have added several small examples of usage promoting its usability.

Should the section recommend using other dedicated packages for parsing: fire, click, docopt? urllib.request does this for the requests package.
