This example shows a Python script that transforms lists of integers through three sequential exercises. It demonstrates custom list-processing functions that swap adjacent elements or replace multiples of five with the preceding value, and it uses conditional logic to apply these transformations based on user input. The code relies on Python’s built-in `raw_input`, `range`, and `format` methods to gather data and print results. It illustrates procedural programming with clear step-by-step comments and control flow via `if`, `for`, and `break` statements.
