Test if the end of each string element matches a pattern.
Equivalent to str.endswith().
Character sequence or tuple of strings. Regular expressions are not accepted.
Object shown if element tested is not a string. The default depends on dtype of the array. For object-dtype, numpy.nan is used. For the nullable StringDtype, pandas.NA is used. For the "str" dtype, False is used.
A Series of booleans indicating whether the given pattern matches the end of each string element.
