"Ну и как же нам перекидывать строки ви числа?" спросите вы. Проверять каждый символ, очистив строку от лишних знаков и точек. Потом конвертить допустимые символы в числа и восстанавливать знак, дробную чусть и тд???
Самый быстрый способ это просто "попробовать" 😜
text = "-0.3"
try:
num = float(text)
except ValueError:
print('Dough!')
Всё остальное это уже парсинг и разбор символов для иных целей.
