Write a program that will announce the appearance of something off the larboard bow to the captain of the ship. Note that you need to a before a word starting with a consonant:

$ ./crowsnest.py narwhalAhoy, Captain, a narwhal off the larboard bow!

Or an before a word starting with a vowel:

$ ./crowsnest.py octopusAhoy, Captain, an octopus off the larboard bow!

Given no arguments, the program should print a brief usage:

$ ./crowsnest.pyusage: crowsnest.py [-h] strcrowsnest.py: error: the following arguments are required: str

It should print a longer usage for -h and --help:

$ ./crowsnest.py -husage: crowsnest.py [-h] strCrow's Nest -- choose the correct articlepositional arguments:  str         A wordoptional arguments:  -h, --help  show this help message and exit

A passing test suite looks like this:
