5.5.3.2 Idiomatic

unique_surnames = set(employee_surnames) def display(elements, output_format='html'): if output_format == 'std_out': for element in elements: print(element) elif output_format == 'html': as_html = '<ul>' for element in elements: as_html += '<li>{}</li>'.format(element) return as_html + '</ul>' else: raise RuntimeError('Unknown format {}'.format(output_format))
