"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. #basic

https://docs.python.org/3/library/functools.html#functools.partialmethod class #functools.partialmethod(func, *args, **keywords) Return a new #partialmethod descriptor which behaves like partial except that it is designed to be used as a method definition rather than being directly callable. func must be a descriptor or a callable (objects which are both, like normal functions, are handled as descriptors). When func is a descriptor (such as a normal Python function, classmethod(), staticmethod(), abstractmethod() or another instance of partialmethod), calls to __get__ are delegated to the underlying descriptor, and an appropriate partial object returned as the result. When func is a non-descriptor callable, an appropriate bound method is created dynamically. This behaves like a normal Python function when used as a method: the self argument will be inserted as the first positional argument, even before the args and keywords supplied to the partialmethod constructor.
