Метод строки isidentifier() поможет узнать, подходит ли данная строка в качестве имени объекта.
Вполне может заменить самостоятельно придуманную регулярку.
>>> 'some_name'.isidentifier()
True
Обычное имя переменной
>>> '私は手紙です'.isidentifier()
True
Юникод в качестве имени тоже доступен
>>> '1_name'.isidentifier()
False
Имя не может начинаться с цифры
>>> '੬_name'.isidentifier()
False
Включая все цифры юникода
>>> 'some name'.isidentifier()
False
Пробелы недопустимы

A red blood cell count measures how many red blood cells are in a tiny drop of your blood (one microliter).
Normal ranges:
- Men: 4.0 to 5.9 million cells per microliter
- Women: 3.8 to 5.2 million cells per microliter.
To help you picture it: a microliter is about the size of a small grain of sand.
Low counts may mean anemia. High counts may be from smoking or dehydration.

The biconcave shape of red blood cells maximizes surface area for efficient oxygen exchange and allows flexibility to squeeze through tiny capillaries, crucial for health. Diseases can distort this shape, but new microfluidic tech helps detect these changes for better diagnosis. 🔬💉🩸
