Which function helps you create a set of instructions to be reused in Karel programming?

The function that assists in creating a set of instructions to be reused in Karel programming is the one that defines a function. When you define a function, you encapsulate a series of commands under a single name, allowing you to execute that block of instructions multiple times throughout your program without needing to rewrite the code repeatedly. This promotes code efficiency, readability, and ease of debugging.

Defining functions is a fundamental aspect of programming, as it helps to make your code more organized and modular. By breaking your program into smaller, reusable pieces, you can simplify complex tasks and enhance maintainability. This is especially useful in Karel programming, where you often need to perform repetitive tasks or execute similar sequences of commands in different parts of your program.
