Sometimes, we want to get the index of the returned max or min item using max()/min() on a list with Python.
In this article, we’ll look at how to get the index of the returned max or min item using max()/min() on a list with Python.
How to get the index of the returned max or min item using max()/min() on a list with Python?
To get the index of the returned max or min item using max()/min() on a list with Python, we can use the values.__getitem__ method as the value of the key parameter of min.
For instance, we write:
values = [1, 2, 3, 4, 5]
index_min = min(range(len(values)), key=values.__getitem__)
print(index_min)
We call min with range(len(values)) to get the min index of the item with the lowest value in the values list.
And we set key to values.__getitem__ to get the value from the index in the range(len(values)) generator so we can use the values in the values list for comparison.
Therefore, index_min is 0.
Conclusion
To get the index of the returned max or min item using max()/min() on a list with Python, we can use the values.__getitem__ method as the value of the key parameter of min.
