pandas.Index.get_loc

Index.get_loc(key, method=None)

Get integer location for requested label

Parameters:

key : label

method : {None, ‘pad’/’ffill’, ‘backfill’/’bfill’, ‘nearest’}

• default: exact matches only.
• pad / ffill: find the PREVIOUS index value if no exact match.
• backfill / bfill: use NEXT index value if no exact match
• nearest: use the NEAREST index value if no exact match. Tied distances are broken by preferring the larger index value.

Returns:

loc : int if unique index, possibly slice or mask if not
