Great code! Short and clear. The specification of ValueError is also very pythonic ("explicit is better than implicit" =]). An alternative to replace() would also be to check whether 'e' is in val: <a href="https://py.checkio.org/mission/is-string-a-number-part-ii/publications/entreoutros/python-3/try-except-e-not-in-val/">https://py.checkio.org/mission/is-string-a-number-part-ii/publications/entreoutros/python-3/try-except-e-not-in-val/</a>
