# numpy.strings.rstrip

strings.rstrip(a, chars=None)

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

  Parameters:
    a array-like, with `StringDType`, `bytes_`, or `str_` dtype
    chars scalar with the same dtype as `a`, optional

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

  Returns:
    out ndarray

      Output array of `StringDType`, `bytes_` or `str_` dtype, depending on input types

      array(['aAaAaA', 'abBABba'], dtype='<U7')
      >>> np.strings.rstrip(c, 'a')
      array(['aAaAaA', 'abBABb'], dtype='<U7')
      >>> np.strings.rstrip(c, 'A')
      array(['aAaAa', 'abBABba'], dtype='<U7')
