(03.01 LC) What is one benefit of using Python's Turtle Graphics Module?

Importing pre-written code to draw on the screen makes a programmer's job faster and more efficient.

Use relational operators to indicate test conditions.

(02.04 MC) How does the waterfall method of software development differ from the agile method?
