Adding arbitrary arguments

Python allows custom functions to accept any number of positional arguments through the use of "Arbitrary arguments". This flexibility enables functions to be used in a variety of ways while still producing the expected results.

Using this power, you'll build a function that concatenates (joins together) strings, regardless of how many blocks of text are provided!
