numpy.core.defchararray.rstrip

numpy.core.defchararray.rstrip(a, chars=None)[源代码]

For each element in a, return a copy with the trailing characters removed.

Calls str.rstrip element-wise.

Parameters:
a : array-like of str or unicode
chars : str or unicode, optional

The chars argument is a string specifying the set of characters to be removed. If omitted or None, the chars argument defaults to removing whitespace. The chars argument is not a suffix; rather, all combinations of its values are stripped.

Returns:
out : ndarray

Output array of str or unicode, depending on input type
