• Define a function that accepts arguments.
• Create a default argument.
• Practice returning a value.

• Interpreter: a program that executes other programs. Python programs require the Python interpreter to be installed on your computer so that they can be run.
• Python Shell: an interactive interpreter that can be accessed from the command line.
• Data Type: a specific kind of data. The Python interpreter uses these types to determine which actions can be performed on different data items.
• Exception: a type of error that can be predicted and handled without causing a program to crash.
• Code Block: a collection of code that is interpreted together. Python groups code blocks by indentation level.
• Function: a named code block that performs a sequence of actions when it is called.
• Scope: the area in your program where a specific variable can be called.

This is a test-driven lab. Run pipenv install to create your virtual environment and pipenv shell to enter the virtual environment. Then run pytest -x to run your tests. Use these instructions and pytest's error messages to complete your work in the lib/ folder.

In this lab, you'll be defining a function called parrot().

The parrot() function should accept an argument of a string and both print() and return the string at the end of the function.

The parrot() function should have a default argument of "Squawk!"

NOTE: This lab is explicitly testing your ability to control the return value of a function: not just what it does, but what it returns. Remember, return values are important. What's the return value of print()?
