Changelist
This PR adds a Python command-line tool (cow.py) that replicates the classic cowsay functionality using the cowsay library.
Why
To provide a fun but practical example of wrapping a Python library into a CLI tool, with proper argument parsing and dynamic options.
How
Added argparse support for user input.
Accepts a message (positional argument) and an optional --animal flag.
Dynamically fetches supported animals from cowsay.char_names (no hardcoding).
Defaults to the cow character if no animal is specified.
Outputs ASCII art with the text “spoken” by the chosen animal.
Includes built-in --help with clear usage instructions.
Testing
Run python3 cow.py "Hello world!" → cow output.
Run python3 cow.py --animal turtle "Fish are cool!" → turtle output.
Run python3 cow.py --help → displays usage and available animals.
