<pre class='brush: python'>d, m = divmod(r.numerator, r.denominator) --> d, m = divmod(*r.as_integer_ratio()) </pre> <p>good idea with 'not m and d or' instead of '... if m else d', and and so on. But, imho, it's loss of clearness</p> <pre class='brush: python'>return not m and d or (d and f'{d} and ' or '') + f'{r - d}' --> return f'{d and f"{d} and " or ""}{f - d}' if m else d --> return f'{f"{d} and " if d else ""}{f - d}' if m else d </pre>
