The **`isnumeric()` method** is a string function in Python that is used to find whether or not all the characters given in a string are numeric. The numeric characters include: 

* The numbers 0-9
* Subscript & superscript
* #key# Unicode numeric value properties :like  fractions, roman numerals, and currency numerators #key#


# Syntax

```Python
string.isnumeric()
```

## Return value

* If all the given characters in the string are numeric, the `isnumeric` method will return `True`.

* If any one of the characters in the given string is not numeric, the `isnumeric` method will return `False`.

num = '123'
print( num , 'isnumeric -- ', num.isnumeric())

num = '2\u00B2' #equivalent for 2² 
print( num , 'isnumeric -- ', num.isnumeric())

num = '½'
print( num , 'isnumeric -- ', num.isnumeric())

num='12a'
print( num , 'isnumeric -- ', num.isnumeric())

* In the first one, `123` is used as a string. All the characters are numeric in the string, so the output that will be displayed is `True`.

* In the second one, `2\u00B2` is used as a string that is equivalent to ` 2²` (superscript is also a numeric character). All the characters are numeric in the string, so the output that will be displayed is `True`.

* In the third one, `½` is used as a string that is a fractional number (the fractional number is also a numeric character). All the characters are numeric in the string, so the output that will be displayed is `True`.

* In the fourth one, `12a` is used as a string, where `a` in the string is not numeric, so `False` will be returned.
