Pandas Series: str.isdecimal() function

Series-str.isdecimal() function

The str.isdecimal() function is used to check whether all characters in each string are decimal or not.
This is equivalent to running the Python string method str.isdecimal() for each element of the Series/Index. If a string has zero characters, False is returned for that check.

Syntax:

Series.str.isdecimal(self)

Returns: Series or Index of bool
Series or Index of boolean values with the same length as the original Series/Index.

More Detailed Checks for Numeric Characters

There are several different but overlapping sets of numeric characters that can be checked for.

Example - The s1.str.isdecimal method checks for characters used to form numbers in base 10:

Python-Pandas Code:

import numpy as np
import pandas as pd
s1 = pd.Series(['22', '³', '⅕', ''])
s1.str.isdecimal()

Output:

0     True
1    False
2    False
3    False
dtype: bool
