В продолжение прошлого поста про цифры в мире строк. Почему методы isdigit() и isnumeric() не определяют в строке float и отрицательные значения? Дело в том, что эти методы работают с ЦИФРАМИ, то есть с единичным символом. А строка "-2" или "3.4" это уже ЧИСЛО. То есть не символ а значение, записанное несколькими символами. Все озвученные методы проходятся по каждому символу строки и проверяют их индивидуально. В юникоде есть символы цифр с точками "🄀⒈⒉⒊⒋⒌⒍⒎⒏⒐" Каждая из них это ОДИН СИМВОЛ, поэтому он будет считаться цифрой >>> '⒌'.isdigit(), '⒌'.isnumeric() True, True Но когда мы пишем это выражение в два символа ( 5+точка), то это не работает. >>> '5.'.isdigit(), '5.'.isnumeric() False, False А еще есть такие символы >>> '⑴⑵⑶⑷⑸'.isdigit() True >>> '🄁🄂🄃'.isdigit() True Но они не преобразуются в десятичные цифры >>> '⒈'.isdecimal() False >>> '🄃'.isdecimal() False >>> '⑶'.isdecimal() False #basic
