## Python String : isdecimal()

#### Syntax :

string.isdecimal()

## Parameter Values :

The isdecimal() doesn't take any parameters.

#### Returns :

The isdecimal() returns:

• True if all characters in the string are decimal characters.
• False if at least one character is not decimal character.

Sample Code :

1.
`string = "28212"print(string.isdecimal())# contains alphabetsstring = "32ladk3"print(string.isdecimal())# contains alphabets and spacesstring = "Mo3 nicaG el l22er"print(string.isdecimal())`
Output :
True
False
False

The superscript and subscripts are considered digit characters but not decimals. If the string contains these characters (usually written using unicode), isdecimal() returns False.

Similarly, roman numerals, currency numerators and fractions are considered numeric numbers (usually written using unicode) but not decimals. The isdecimal() also returns False in this case.

There are two methods `isdigit()` and `isnumeric()` that checks whether the string contains digit characters and numeric characters respectively.

2.
`string = '23455'print(string.isdecimal())#s = '%uFFFD3455'string = '%uFFFD3455'print(string.isdecimal())# s = '%uFFFD'string = '%uFFFD'print(string.isdecimal())`
Output :
True
False
False

Hence,we can see above function isdecimal() returns true if all characters in a string are decimal characters. If not, it returns False.
