# numpy.char.rstrip

char.rstrip(a, chars=None)

  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
