     1. Lists all Python files in the current directory that contain "example" in their name.
     2. If no command-line arguments are provided, it prints the list of example files and prompts the user to select one by index.
-    3. If a command-line argument is provided, it uses that as the index of the example file to run.
-    4. Validates the selected index and either exits, prints an error message, or imports and runs the selected example's main function.
