How to find “maximum” value in a “List” and to extract the respective row data

arr = [E1, E2, E3, E4, E5, E6]

E1 = [ 1, 2, 3, 4, 5, 6 ]

E2 = [ 10, 0.2, 23, 14, 85, 5 ]

E3 = [ 11, 21, 13, 14, 51,7 ]

E4 = [ 12, 22, 13, 24, 15,41 ]

E5 = [ 51, 26, 32, 41, 15, 65 ]

E6 = [ 11, 2, 13, 4, 15, 7 ]

max(E6) = 15

(row of the 15)

print 5, 85, 51, 15, 15, 15

Can someone please help me with this:

I have 6 lists. I want to find a maximum value in one column (one list) and to extract the respective row data (as described above).

Thanks in advance

Consider you have a list of list like this

arr = [[0, 5, 1, 2, 4, 3], [5, 4, 2, 0, 1, 3], [4, 1, 0, 3, 5, 2], [2, 1, 0, 3, 4, 5], [1, 5, 2, 0, 3, 4], [2, 1, 4, 5, 3, 0]]


To get the row on which the 6th column value is max, first sort the array in reversed order, based on 6th column and the get the first element

from operator import itemgetter
sorted(arr, key=itemgetter(5), reverse=True)[0]
# [2, 1, 0, 3, 4, 5]
