bigframes.pandas.api.typing.StringMethods.isnumeric

StringMethods.isnumeric() → T

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.

Examples:

>>> import bigframes.pandas as bpd

>>> s1 = bpd.Series(['one', 'one1', '1', ''])
>>> s1.str.isnumeric()
0    False
1    False
2     True
3    False
dtype: boolean

Returns:

Series or Index of boolean values with the

same length as the original Series/Index.

Return type:

bigframes.series.Series
