Since the argument is actually optional, no error is thrown when running the program without --verbose. Note that by using .default_value(false), if the optional argument isn’t used, it's value is automatically set to false. By using .implicit_value(true), the user specifies that this ...

If you provide the option at the command line, then its value will be True. If you miss the option, then its value will be False. You’ll learn more about the action argument to .add_argument() in the Setting the Action Behind an Option section. The build_output() function on line...
