Definition and Usage
The isnumeric() method returns True if all the
characters are numeric (0-9), otherwise False.
Exponents, like ² and ¾ are also considered to be numeric values.
"-1" and "1.5" are NOT considered numeric values,
because all the characters in the string must be numeric, and the - and the . are not.
Syntax
string.isnumeric()
Parameter Values
No parameters.
