.isdigit()

The .isdigit() method under the string class checks if all the elements in the string are digits; applicable elements also include special cases like compatibility superscript digits (¹, ², ³, etc.). The method returns True in the mentioned cases and must not be an empty string, otherwise, it returns False.
