cudf.core.column.string.StringMethods.isdigit#

StringMethods.isdigit() → SeriesOrIndex#

Check whether all characters in each string are digits.

This is equivalent to running the Python string method str.isdigit() 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

>>> import cudf
>>> s = cudf.Series(['23', '³', '⅕', ''])

The s.str.isdigit method is the same as s.str.isdecimal but also includes special digits, like superscripted and subscripted digits in unicode.

>>> s.str.isdigit()
0     True
1     True
2    False
3    False
