For example [1,2,3,4,1,2]
has min element 1, but it occurs for the last time at index 4.
len(myList)-1 - myList[::-1].index(min(list))
This uses the slice notation list[::-1]
to return a shallow copy of a reversed list, so that it doesn't change your original list, then searches for the minimum value in that list
>>>myList = [1,2,3,4,1,2]
>>>len(myList)-1 - myList[::-1].index(min(list))
4
