There is No Argmax Function for Python List | by Eden Au | Towards Data Science | Dear Python programmers,
Given a Python list l = [50, 99, 67, 99, 48], how do you find the argmax of the list? Turns out there is no built-in argmax function for Python list! You can’t just do argmax(l) or max(l).index. The first thing I can think of is to convert the list to a numpy array, or pandas DataFrame, or even... | [
