Finding The Largest Number in a Nested List in Python

Question

I would like to put the max number(s) to a new array, I\'ve tried every thing that I can think of and none seem to work....(adding to an empty result array, concat, etc)

Answer 1

Try a list comprehension:

L = [[21, 34, 345, 2], [555, 22, 6, 7], [94, 777, 65, 1], [23, 54, 12, 666]]
maxes = [max(sublist) for sublist in L]
print(maxes)
# [345, 555, 777, 666]
