bigframes.pandas.MultiIndex.all# MultiIndex.all() → bool# Return whether all elements are Truthy. Examples: True, because nonzero integers are considered True. >>> bool(bpd.Index([1, 2, 3]).all()) True False, because 0 is considered False. >>> bool(bpd.Index([0, 1, 2]).all()) False Returns: A single element array-like may be converted to bool. Return type: bool Raises: TypeError – MultiIndex with more than 1 level does not support all.
