How to print the highest number in lists that are inside another list

I want to print the highest number from my list (1231 here).
I tried doing this here (posted below), but that doesn’t work. It just shows the highest total number for each element in my list, which is, obviously, not what I want.

list = [ [1,3,251], [2], [1231,52,22] ]

for i in range(len(list)):
    for j in range(len(list[i])):
        print(max(list))

prints:

[1231, 52, 22]
[1231, 52, 22]
[1231, 52, 22]
[1231, 52, 22]
[1231, 52, 22]
[1231, 52, 22]
[1231, 52, 22]

>Solution :

list = [ [1,3,251], [2], [1231,52,22] ]
new_list = []
for i in list:
    new_list.append(max(i))
print(max(new_list))

This will do. This will print only the highest number from the entire list.
