format – A string, an iterable of strings, or a mapping of labels to strings. For 1D containers, an iterable of strings must be of length equal to the container; a mapping can use Index labels (for a Series) or positions (for an Index). For 2D containers, an iterable of strings must be of length equal to the columns (for a Frame) or the depth (for an Index Hierarchy); a mapping can use column labels (for a Frame) or depths (for an IndexHierarchy).
