parameters: (a, chars=None)
return_statement: return _vec_string(a_arr, a_arr.dtype, 'rstrip', (chars,))
docstring: 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

      --------
      str.rstrip
  
      Examples
      --------
      >>> c = np.array(['aAaAaA', 'abBABba'], dtype='S7'); c
      array(['aAaAaA', 'abBABba'],

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