How to find all positions of the maximum value in a list?
...>>> a = [3,2,1, 4,5]
Using the generator enumerate and making a casting
>>> list(enumerate(a))
[(0, 3), (1, 2), (2, 1), (3, 4), (4, 5)]
At this point, we can extract the position of max with
>>> max(enumerate(a), key=(lambda x: x[1]))
(4, 5)
The above tells us, th...
