cudf.core.column.string.StringMethods.is_vowel#

StringMethods.is_vowel(position) → SeriesOrIndex[source]#

Return true for strings where the character at position is a vowel – not a consonant. The position parameter may also be a list of integers to check different characters per string. If the position is larger than the string length, False is returned for that string.

Parameters:

position: int or list-like: The character position to check within each string.

Returns:

Series or Index of bool dtype.

>>> positions = cudf.Series([2, 3])
>>> ser.str.is_vowel(positions)
