You can use these methods to get the index labels for the minimum or maximum values of a Series or DataFrame. Suppose you want to know - which day of the last week had the lowest sales amount? The method idxmin will get you the answer:. Thus the lowest sales of the week occurred on Tuesday. And what was that amount? The Series method idxmax returns the index of the maximum value. What if the dataset contains the minimum or maximum value more than once? How would the methods idxmin or idxmax behave? Suppose you calculate the average sales per weekday for the last year. And store them in a pandas Series :. The minimum value, , occurs twice on Tuesday and Thursday. The maximum value, , is repeated on Sunday and Saturday. We expect the method idxmin to return multiple index labels. But it only returns Tuesday , the row label of the first occurrence of the minimum value :. So idxmin failed to get us all the days when the minimum value occurred.
