Index.max(axis=None, skipna=True, *args, **kwargs)

  The maximum is computed by comparing all values in the Index. NA/null values are excluded by default.

  Parameters:

      For compatibility with NumPy. Only 0 or None are allowed.

    skipna bool, default True

      Exclude NA/null values when showing the result.

    *args, **kwargs

      Additional arguments and keywords for compatibility with NumPy.

  Examples

      >>> idx = pd.Index([3, 2, 1])
      >>> idx.max()
      3

      >>> idx = pd.Index(["c", "b", "a"])
      >>> idx.max()
      'c'

  For a MultiIndex, the maximum is determined lexicographically.

      >>> idx = pd.MultiIndex.from_product([("a", "b"), (2, 1)])
      >>> idx.max()
      ('b', 2)
