Needs updating for Python 3.x

[aspiers]

At the time of writing, Python 2.7 is EOL in under 10 months, but https://python-packaging.readthedocs.io/en/latest/ says:

At this time, this documentation focuses on Python 2.x only, and may not be as applicable to packages targeted to Python 3.x.

So as increasing numbers move to Python 3.x, it needs a sanity check to make sure it's not accidentally misleading people who miss that caveat.

The top section in Command Line Scripts is not working for me - I can only run the script when im INSIDE the /bin/ directory or if i specify the path to the /bin (i.e $ ../bin/funniest-joke )(

Any guidance on this?

Thank you in advance,
AL

P.S. Would be happy to contribute once I'm able to get aforementioned section to work
