pandas.Series.str.isnumeric#

Series.str.isnumeric()[source]#

Check whether all characters in each string are numeric.

This is equivalent to running the Python string method str.isnumeric() for each element of the Series/Index. If a string has zero characters, False is returned for that check.

Returns:

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

Examples

The s.str.isnumeric method is the same as s3.str.isdigit but also includes other characters that can represent quantities such as unicode fractions.

>>> s1 = pd.Series(['one', 'one1', '1', ''])
>>> s1.str.isnumeric()
0    False
1    False
