What is the principle of procedural abstraction as applied to function definitions?

Question: Explain the principle of procedural abstraction as applied to function definitions and provide an example. Answer: Procedural abstraction is a concept that simplifies complex tasks by breaking them into smaller subtasks using separate procedures (or functions/methods) for each subtask. This makes the code more organized, clear, and reusable. In function definitions, procedural abstraction involves creating a function to perform a specific task, allowing it to be reused across the program without repeating code. For example, consider a program calculating the square of a number multiple times. Instead of writing the calculation code every time, we create a function to calculate the square like this: ```python def square(number): return number ** 2 result1 = square(5) # Output: 25 result2 = square(8) # Output: 64 result3 = square(12) # Output: 144 ``` The function, `square`, can now be reused throughout the code, making it more organized and easier to maintain.
