# numpy.char.strip

char.strip(a, chars=None)

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

  Calls str.strip 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 prefix or suffix; rather, all combinations of its values are stripped.

  Returns:
    out ndarray

      Output array of str or unicode, depending on input type

  Examples

      >>> c = np.array(['aAaAaA', '  aA  ', 'abBABba'])
      >>> c
      array(['aAaAaA', '  aA  ', 'abBABba'], dtype='<U7')
      >>> np.char.strip(c)
      array(['aAaAaA', 'aA', 'abBABba'], dtype='<U7')
      >>> np.char.strip(c, 'a') # 'a' unstripped from c[1] because whitespace leads
      array(['AaAaA', '  aA  ', 'bBABb'], dtype='<U7')
      >>> np.char.strip(c, 'A') # 'A' unstripped from c[1] because (unprinted) ws trails
      array(['aAaAa', '  aA  ', 'abBABba'], dtype='<U7')
